| haemagglutinin-neuraminidase protein | <protein> A protein found in the capsid of the Sendai virus which is exceptionally good at binding to the cytoplasmic membranes of many animal cells. The protein is therefore used to make fusogenic vesicles for the purpose of delivering therapeutic drugs or other chemicals directly into cells. (09 Oct 1997) |
|---|---|
| crude protein | Incomplete proteins which lack essential amino acids. (09 Oct 1997) |
| crystalline protein | <protein> The major protein found in the lens of the vertebrate eye, it can be dissolved in water easily. (09 Oct 1997) |
| Csk-like protein-tyrosine kinase | <enzyme> Phosphorylates c-terminal conserved tyr of src family members; from mouse brain; has 52% identity with mouse csk; mw 52 kD; genbank u05210 Registry number: EC 2.7.1.- Synonym: ctk (kinase), ctk gene product, csk-type protein-tyrosine kinase, ntk (kinase), bhk (kinase) (26 Jun 1999) |
| C-terminal leucine protein methyltransferase | <enzyme> Reversibly modifies protein phosphatase 2a by methyl esterification at its c-terminal leucine residues Registry number: EC 2.1.1.- Synonym: tlp methyltransferase (26 Jun 1999) |
| PP5 protein-serine-threonine phosphatase | <enzyme> Has 4 tetratricopeptide repeat (tpr) motifs; similar to ppt1 protein; do not confuse with the placental protein pp5; amino acid sequence given in first source Registry number: EC 3.1.3.- Synonym: pp5 phosphatase, protein phosphatase 5 (26 Jun 1999) |
| pp65 protein | <protein> A protein made by a cytomegalovirus which prevents the cell that the virus has infected from displaying fragments of viral proteins, called antigens, on the cells surface. In this way the cytomegalovirus is able to evade the bodys immune system, more or less permanently. (09 Oct 1997) |
| P protein | <protein> Protein found in large amounts in phloem seive tubes. Appears as thin strands when seen in the electron microscope. (18 Nov 1997) |
| cyclic AMP-dependent protein kinase | Enzymes which attach phosphate groups to the serine or tyrosine amino acids on proteins as a means of regulating the proteins' activity in metabolic reactions. (09 Oct 1997) |
| cyclic AMP receptor protein | A transcriptional regulator in prokaryotes which, when activated by binding cyclic AMP, acts at several promoters. Cyclic AMP receptor protein was originally identified as a catabolite gene activator protein. It was subsequently shown to regulate several functions unrelated to catabolism, and to be both a negative and a positive regulator of transcription. Cell surface cyclic AMP receptors are not included (cyclic AMP receptors), nor are the eukaryotic cytoplasmic cyclic AMP receptor proteins, which are the regulatory subunits of cyclic AMP-dependent protein kinases. (12 Dec 1998) |
| pregnancy-associated alpha-plasma protein | An alpha 2-macroglobulin, molecular weight approximately 750,000 now believed to be a pregnancy-specific protein. Its plasma levels increase steadily during the second trimester and continue to rise until the end of gestation. (12 Dec 1998) |
| pregnancy-associated beta-plasma protein | A beta-globulin now believed to be a pregnancy-specific protein. Its plasma levels increase steadily during pregnancy until the end of gestation. (12 Dec 1998) |
| cysteine string protein | <protein> (CSPs) Peripheral membrane proteins that contain more than 10 palmitoylated cysteines and a DNA J homology domain. Nature 375:647 (18 Nov 1997) |
| SA-induced protein kinase | <enzyme> 48-kD map kinase isolated from nicotiana tabacum; genbank u94192 Registry number: EC 2.7.10.- Synonym: p48 sip kinase, salicylic acid-induced protein kinase, sipk enzyme (26 Jun 1999) |
| prion protein | Small, infectious proteinaceous particle, of non-nucleic acid composition because of its resistance to nucleases; the causative agent, either on a sporadic, genetic, or infectious basis, of six neurodegenerative diseases in animals, and four in humans; the latter include the spongiform encephalopathies of kuru, Creutzfeldt-Jakob disease, Gerstmann-Straussler-Scheinker syndrome and fatal familial insomnia. The gene encoding for the PrP is found on chromosome 20. Synonym: prion. (05 Mar 2000) |
