| p35 | <protein> Group of calcium-binding proteins that interact with acidic membrane phospholipids in membranes. They contain 4 or 8 repeats of a 61 amino acid domain that folds into 5 a helices. Also known by several other names (e.g. Lipocortins, endonexins), reflecting the history of their discovery in different contexts. See: lipocortin, endonexin I & II, calpactin, p70 and calelectrin.

| P400 protein | <protein> Inositol 1,4, 5 triphosphate receptor (InsP3 R). Key protein to understanding mechanisms of InsP3 mediated Ca mobilisation. Originally found as a cerebellar glycoprotein of 250 kD and subsequently shown to be identical to the InsP3 receptor protein. (18 Nov 1997) |
| p42(mapk) kinase | <enzyme> A proline-directed serine/threonine kinase which mediates signal transduction from the cell surface to the nucleus. Activation of the enzyme by phosphorylation leads to translocation into the nucleus and phosphorylation of certain transcription factors. Registry number: EC 2.7.10.- (12 Dec 1998) |
| p49 3F12 kinase | <enzyme> Expressed in the nervous system; autophosphorylates both threonine and tyrosine residues; shows 43% amino acid sequence identity to p42(mapk); amino acid sequence given in first source Registry number: EC 2.7.1.- Synonym: p49(3f12) kinase, mitogen activated protein kinase p49(3f12), map kinase p49(3f12), p49(3f12) sap kinase (26 Jun 1999) |
| p53 | <molecular biology, oncogene> A gene which encodes a protein that regulates cell growth and is able to cause potentially cancerous cells to destroy themselves. In humans it is a 393 residue phosphoprotein that is a tumour suppressor gene rather than an oncogene, as it is frequently inactivated or mutated in tumours and transformed cells. The gene is an antioncogene, and is often found mutated in smokers with lung cancer by a compound found in tobacco smoke, a polycyclic aromatic hydrocarbon called benzo[a]pyrene. The protein it encodes is a phosphoprotein that is 53 kilodaltons in mass. (24 Mar 1998) |
| p53-activating kinase | <enzyme> Regulates p53 activity in saccharomyces cerevisiae; 810 amino acid residues; genbank u24167; do not confuse with pak I, protease-activated kinase Registry number: EC 2.7.10.- Synonym: pak1 gene product, yeast pak1 (26 Jun 1999) |
| p54 protein kinase | <enzyme> A stress-activated kinase related to erk-1 and erk-2 but activated preferentially by heat shock, protein-synthesis inhibitors and thf-alpha; phosphorylates c-jun proteins; genbank l27111 Registry number: EC 2.7.10.- Synonym: p54 map kinase (26 Jun 1999) |
