| intestinal calcium-binding protein | <protein> Calcium-binding proteins containing the EF hand motif, induced by vitamin D3. (18 Nov 1997) |
|---|---|
| invA protein | <chemical> Amino acid sequence given in first source; required for salmonella to invade epithelial cells Synonym: inva gene product (05 Dec 1998) |
| iron-storage protein | <chemical> Soluble iron storage protein from e coli; different from ferritin and haemosiderin (05 Dec 1998) |
| iron succinyl milk protein complex | <chemical> Soluble iron complex with 5% iron content produced by reacting succinylated milk protein and ferric chloride Synonym: iron succinyl protein complex, itf 282, itf-282 (05 Dec 1998) |
| islet cell antigen-related protein-tyrosine phosphatase | <enzyme> Receptor-like autoantigen found in insulin-dependent diabetes; genbank l76258 Registry number: EC 3.1.3.- Synonym: iar ptp (26 Jun 1999) |
| islet neogenesis-associated protein | <chemical> Constituent of ilotropin; stimulates proliferation of pancreatic ductal cells in vitro; from hamsters and humans; amino acid sequence given in first source Synonym: ingap protein, ingap gene product (05 Dec 1998) |
| octamer binding protein | <protein> Transcription factor that binds to the octamer motif. Examples: mammalian proteins Oct 1, Oct 2. (18 Nov 1997) |
| odourant binding protein | Proteins in nasal mucus that bind lipophilic odour-producing molecules and transfer them to the olfactory receptors. Similar proteins may mediate taste. (05 Mar 2000) |
| oligomeric protein | <biochemistry> A protein where two or more of its units are identical polypeptide chains. (09 Oct 1997) |
| oligomycin sensitivity conferral protein | <protein> The _ subunit of the ATP synthase, believed to link the F1 catalytic segment to the F0 proton conduction segment. Binds the toxin oligomycin. (18 Nov 1997) |
| oncogene protein gp140(v-fms) | Transforming glycoprotein coded by the fms oncogene from the susan mcdonough strain of feline sarcoma virus (sm-fesv). The oncogene protein v-fms lacks sequences, which, in the highly homologous proto-oncogene protein c-fms (csf-1 receptor), normally serve to regulate its tyrosine kinase activity. The missing sequences in v-fms mimic the effect of ligand and lead to constitutive cell growth. The protein gp120(v-fms) is post-translationally modified to generate gp140(v-fms). (12 Dec 1998) |
| oncogene protein p21(ras) | Transforming protein encoded by ras oncogenes. Point mutations in the cellular ras gene (c-ras) can also result in a mutant p21 protein that can transform mammalian cells. Oncogene protein p21(ras) has been directly implicated in human neoplasms, perhaps accounting for as much as 15-20% of all human tumours. (12 Dec 1998) |
| oncogene protein p55(v-myc) | Transforming protein coded by myc oncogenes. The v-myc protein has been found in several replication-defective avian retrovirus isolates which induce a broad spectrum of malignancies. (12 Dec 1998) |
| oncogene protein p65(gag-jun) | Transforming protein coded by jun oncogenes (genes, jun). This is a gag-onc fusion protein of about 65 kD derived from avian sarcoma virus. V-jun lacks a negative regulatory domain that regulates transcription in c-jun. (12 Dec 1998) |
| oncogene protein pp60(v-src) | <chemical> Tyrosine-specific protein kinase encoded by the v-src oncogene of rous sarcoma virus. The transforming activity of pp60(v-src) depends on both the lack of a critical carboxy-terminal tyrosine phosphorylation site at position 527, and the attachment of pp60(v-src) to the plasma membrane which is accomplished by myristylation of its n-terminal glycine. Chemical name: Kinase (phosphorylating), protein pp60src (12 Dec 1998) |
