PNP

Homo sapiens (Human)

PNP; Inosine phosphorylase

PNP/MTAP phosphorylase family

Pentosyltransferase

The purine nucleoside phosphorylases catalyze the phosphorolytic breakdown of the N-glycosidic bond in the beta- (deoxy)ribonucleoside molecules, with the formation of the corresponding free purine bases and pentose-1-phosphate.

Purine nucleoside phosphorylase deficiency (PNPD) [MIM:613179]: A disorder that interrupts both the catabolism of inosine into hypoxanthine and guanosine into guanine, and leads to the accumulation of guanosine, inosine, and their deoxified by-products. The main clinical presentation is recurrent infections due to severe T-cell immunodeficiency. Some patients also have neurologic impairment. {ECO:0000269|PubMed:1384322, ECO:0000269|PubMed:3029074, ECO:0000269|PubMed:8931706}.

Myotonia is characterized by sustained muscle tensing that prevents muscles from relaxing normally. It causes muscle stiffness that can interfere with movement. In some people the stiffness is very mild, while in other cases it may be severe enough to interfere with walking, running, and other activities of daily life. Myotonia SCN4A-related includes myotonia permanens and myotonia fluctuans. In myotonia permanens, the myotonia is generalized and there is a hypertrophy of the muscle, particularly in the neck and the shoulder. Attacks of severe muscle stiffness of the thoracic muscles may be life threatening due to impaired ventilation. In myotonia fluctuans, the muscle stiffness may fluctuate from day to day, provoked by exercise. {ECO:0000269|PubMed:10218481, ECO:0000269|PubMed:16786525, ECO:0000269|PubMed:16832098, ECO:0000269|PubMed:17212350, ECO:0000269|PubMed:17998485, ECO:0000269|PubMed:18203179, ECO:0000269|PubMed:18337100, ECO:0000269|PubMed:19015483, ECO:0000269|PubMed:19347921, ECO:0000269|PubMed:20076800, ECO:0000269|PubMed:27653901, ECO:0000269|PubMed:8058156, ECO:0000269|PubMed:9392583}.

Myasthenic syndrome, congenital, 6, presynaptic (CMS6) [MIM:254210]: A form of congenital myasthenic syndrome, a group of disorders characterized by failure of neuromuscular transmission, including pre-synaptic, synaptic, and post-synaptic disorders that are not of autoimmune origin. Clinical features are easy fatigability and muscle weakness affecting the axial and limb muscles (with hypotonia in early-onset forms), the ocular muscles (leading to ptosis and ophthalmoplegia), and the facial and bulbar musculature (affecting sucking and swallowing, and leading to dysphonia). The symptoms fluctuate and worsen with physical effort. CMS6 affected individuals have myasthenic symptoms since birth or early infancy, negative tests for anti-AChR antibodies, and abrupt episodic crises with increased weakness, bulbar paralysis, and apnea precipitated by undue exertion, fever, or excitement.

Lynch syndrome 2 (LYNCH2) [MIM:609310]: A form of Lynch syndrome, an autosomal dominant disease associated with marked increase in cancer susceptibility. It is characterized by a familial predisposition to early-onset colorectal carcinoma (CRC) and extra-colonic tumors of the gastrointestinal, urological and female reproductive tracts. Lynch syndrome is reported to be the most common form of inherited colorectal cancer in the Western world. Clinically, it is often divided into two subgroups. Type I is characterized by hereditary predisposition to colorectal cancer, a young age of onset, and carcinoma observed in the proximal colon. Type II is characterized by increased risk for cancers in certain tissues such as the uterus, ovary, breast, stomach, small intestine, skin, and larynx in addition to the colon. Diagnosis of classical Lynch syndrome is based on the Amsterdam criteria: 3 or more relatives affected by colorectal cancer, one a first degree relative of the other two; 2 or more generation affected; 1 or more colorectal cancers presenting before 50 years of age; exclusion of hereditary polyposis syndromes. The term 'suspected Lynch syndrome' or 'incomplete Lynch syndrome' can be used to describe families who do not or only partially fulfill the Amsterdam criteria, but in whom a genetic basis for colon cancer is strongly suspected. {ECO:0000269|PubMed:10323887, ECO:0000269|PubMed:10375096, ECO:0000269|PubMed:10386556, ECO:0000269|PubMed:10413423, ECO:0000269|PubMed:10480359, ECO:0000269|PubMed:10598809, ECO:0000269|PubMed:10627141, ECO:0000269|PubMed:10660333, ECO:0000269|PubMed:10671064, ECO:0000269|PubMed:10713887, ECO:0000269|PubMed:10777691, ECO:0000269|PubMed:10882759, ECO:0000269|PubMed:11139242, ECO:0000269|PubMed:11427529, ECO:0000269|PubMed:11726306, ECO:0000269|PubMed:11748856, ECO:0000269|PubMed:11754112, ECO:0000269|PubMed:11781295, ECO:0000269|PubMed:11793442, ECO:0000269|PubMed:11839723, ECO:0000269|PubMed:11870161, ECO:0000269|PubMed:12095971, ECO:0000269|PubMed:12132870, ECO:0000269|PubMed:12200596, ECO:0000269|PubMed:12362047, ECO:0000269|PubMed:12373605, ECO:0000269|PubMed:12655562, ECO:0000269|PubMed:12658575, ECO:0000269|PubMed:14635101, ECO:0000269|PubMed:14961575, ECO:0000269|PubMed:15064764, ECO:0000269|PubMed:15139004, ECO:0000269|PubMed:15365995, ECO:0000269|PubMed:15365996, ECO:0000269|PubMed:16083711, ECO:0000269|PubMed:16451135, ECO:0000269|PubMed:17301300, ECO:0000269|PubMed:17510385, ECO:0000269|PubMed:18561205, ECO:0000269|PubMed:20020535, ECO:0000269|PubMed:21120944, ECO:0000269|PubMed:22753075, ECO:0000269|PubMed:7757073, ECO:0000269|PubMed:8566964, ECO:0000269|PubMed:8571956, ECO:0000269|PubMed:8574961, ECO:0000269|PubMed:8797773, ECO:0000269|PubMed:8872463, ECO:0000269|PubMed:8993976, ECO:0000269|PubMed:9048925, ECO:0000269|PubMed:9067757, ECO:0000269|PubMed:9218993, ECO:0000269|PubMed:9272156, ECO:0000269|PubMed:9298827, ECO:0000269|PubMed:9311737, ECO:0000269|PubMed:9326924, ECO:0000269|PubMed:9399661, ECO:0000269|PubMed:9559627, ECO:0000269|PubMed:9718327, ECO:0000269|PubMed:9833759, ECO:0000269|PubMed:9927034, ECO:0000269|Ref.5}.

G-protein coupled receptor 3 family

GPCR glutamate

Senses fluctuations in the circulating calcium concentration and modulates the production of parathyroid hormone (PTH) in parathyroid glands. The activity of this receptor is mediated by a G-protein that activates a phosphatidylinositol-calcium second messenger system. The G-protein-coupled receptor activity is activated by a co-agonist mechanism: aromatic amino acids, such as Trp or Phe, act concertedly with divalent cations, such as calcium or magnesium, to achieve full receptor activation. G-protein-coupled receptor that senses changes in the extracellular concentration of calcium ions and plays a key role in maintaining calcium homeostasis.

Hypocalciuric hypercalcemia, familial 1 (HHC1) [MIM:145980]: A form of hypocalciuric hypercalcemia, a disorder of mineral homeostasis that is transmitted as an autosomal dominant trait with a high degree of penetrance. It is characterized biochemically by lifelong elevation of serum calcium concentrations and is associated with inappropriately low urinary calcium excretion and a normal or mildly elevated circulating parathyroid hormone level. Hypermagnesemia is typically present. Affected individuals are usually asymptomatic and the disorder is considered benign. However, chondrocalcinosis and pancreatitis occur in some adults. {ECO:0000269|PubMed:11762699, ECO:0000269|PubMed:15572418, ECO:0000269|PubMed:15579740, ECO:0000269|PubMed:15879434, ECO:0000269|PubMed:16598859, ECO:0000269|PubMed:16740594, ECO:0000269|PubMed:17473068, ECO:0000269|PubMed:17698911, ECO:0000269|PubMed:19179454, ECO:0000269|PubMed:19789209, ECO:0000269|PubMed:21566075, ECO:0000269|PubMed:21643651, ECO:0000269|PubMed:22114145, ECO:0000269|PubMed:23169696, ECO:0000269|PubMed:23966241, ECO:0000269|PubMed:25104082, ECO:0000269|PubMed:25292184, ECO:0000269|PubMed:26386835, ECO:0000269|PubMed:27434672, ECO:0000269|PubMed:7673400, ECO:0000269|PubMed:7726161, ECO:0000269|PubMed:7916660, ECO:0000269|PubMed:8636323, ECO:0000269|PubMed:8702647, ECO:0000269|PubMed:8878438, ECO:0000269|PubMed:9298824}.

Clostridial collagenases are among the most efficient degraders of eukaryotic collagen known; saprophytes use collagen as a carbon source while pathogens additionally digest collagen to aid in host colonization. Has both tripeptidylcarboxypeptidase on Gly-X-Y and endopeptidase activities; the endopeptidase cuts within the triple helix region of collagen while tripeptidylcarboxypeptidase successively digests the exposed ends, thus clostridial collagenases can digest large sections of collagen. Active on soluble type I collagen, insoluble collagen, azocoll, soluble PZ-peptide (all collagenase substrates) and gelatin. The full-length protein has collagenase activity, while the in vivo derived C-terminally truncated shorter versions only act on gelatin. In vitro digestion of soluble calf skin collagen fibrils requires both ColG and ColH; ColG forms missing the second collagen-binding domain are also synergistic with ColH, although their overall efficiency is decreased. The activator domain (residues 119-388) and catalytic subdomain (389-670) open and close around substrate using a Gly-rich hinge (387-397), allowing digestion when the protein is closed. Binding of collagen requires Ca(2+) and is inhibited by EGTA; the collagen-binding domain (CBD, S3a plus S3b) specifically recognizes the triple-helical conformation made by 3 collagen protein chains in the triple-helical region. Isolated CBD (S3a plus S3b) binds collagen fibrils and sheets of many tissues.

Collagen receptor involved in collagen-induced platelet adhesion and activation. Plays a key role in platelet procoagulant activity and subsequent thrombin and fibrin formation. This procoagulant function may contribute to arterial and venous thrombus formation. The signaling pathway involves the FcR gamma-chain, the Src kinases (likely FYN or LYN) and SYK, the adapter protein LAT and leads to the activation of PLCG2.
