| receptor protein-tyrosine kinase | <enzyme> A catalytic protein-tyrosine kinase domain found on the cytoplasmic beta-portion of receptors. Many growth and differentiation factor receptors contain this domain. It is critical for the signal transduction pathways required for mitogenesis, transformation, and cell differentiation. Registry number: EC 2.7.1.- (12 Dec 1998) |
|---|---|
| parathyroid hormonelike protein | A 140 amino acid protein secreted by some cancer cells; it causes hypercalcaemia. (05 Mar 2000) |
| carrier protein | <protein> A protein which transports specific substances through the cell membrane in which it is embedded and into the cell. Different carrier proteins are required to transport different substances, as each one is designed to recognise only one substance, or group of similar substances. (09 Oct 1997) |
| catabolite gene activator protein | <molecular biology, protein> A regulatory protein that triggers the transcription of genes that generate the enzymes bacteria need to usenutrients when glucose isabsent. (16 Mar 1998) |
| catabolite (gene) activator protein | A protein that can be activated by cAMP, whereupon it affects the action of RNA polymerase by binding it with it or near it on the DNA to be transcribed. Synonym: cAMP receptor protein, catabolite gene activator. (05 Mar 2000) |
| matrix Gla protein | A calcium binding protein. (05 Mar 2000) |
| cationic protein | <biochemistry> Proteins of azurophil granules of neutrophils, rich in arginine. A chymotrypsin like protease found in azurophil granules is also very cationic as is cathepsin G and neutrophil elastase. Eosinophil cationic protein (21 kD) is particularly important because it damages schistosomula in vitro. (16 Mar 1998) |
| MCK1 protein kinase | <enzyme> From saccharomyces cerevisiae; involved in transcriptional activation of ime1, stimulation of spore maturation, and facilitation of centromere activity during mitosis; member of the glycogen synthase kinase 3 family; amino acid sequence given in first source Registry number: EC 2.7.1.- Synonym: meiosis and centromere regulatory kinase, ypk1 phosphotyrosyl protein, ypk1 kinase, mck1 gene product (26 Jun 1999) |
| pat1 protein kinase | <enzyme> Negatively regulated by mei3+ gene product Registry number: EC 2.7.1.- Synonym: ran1 protein (26 Jun 1999) |
| glial fibrillary acidic protein | <protein> This protein, found in microfilaments of glial cells, helps distinguish glial from nonglial tumours. A laboratory stain is used to test for its presence. (16 Dec 1997) |
| CCR1 protein kinase | <enzyme> Acts independently of camp-dependent protein kinase and the transcriptional activator adr1 in controlling yeast adh2 expression Registry number: EC 2.7.10.- Synonym: snf1 protein kinase, glc2 protein, glc2 gene product, snf1 gene product (26 Jun 1999) |
| globular protein | <molecular biology> Any protein that adopts a compact morphology is termed globular. Generally applied to proteins in free solution that have a more-or-less spherical shape, but may also be used for compact folded proteins within membranes. (14 Oct 1997) |
| cdc28 protein kinase | <enzyme> A protein kinase encoded by the saccharomyces cerevisiae cdc28 gene and required for progression from the g1 to the s phase in the cell cycle. It is a complex of approximately 160 kD containing a substrate called p40. Registry number: EC 2.7.1.- (12 Dec 1998) |
| cdc2+-CDC28-related protein kinase | <enzyme> From rice; key enzyme for cell cycle regulation in eukaryocytes; belongs to serine-threonine kinase subfamily Registry number: EC 2.7.10.- Synonym: cdc2-cdc28-pk, cdc2-cdc28-rp kinase (26 Jun 1999) |
| CDC5 protein kinase | <enzyme> Phosphorylates the residues that play a crucial role in mitotic function; genes msd2 and cdc5 are identical; 705 aa residues, mw 81 kD genbank m84220 Registry number: EC 2.7.1.- Synonym: cdc5 gene product (26 Jun 1999) |
