| viral regulatory proteins | Proteins which regulate the rate of transcription of viral structural genes. (12 Dec 1998) |
|---|---|
| androgen-binding proteins | Carrier proteins produced in the sertoli cells of the testis, secreted into the seminiferous tubules, and transported via the efferent ducts to the epididymis. Participate in the transport of androgens; include also synthetic androgens binding proteins. (12 Dec 1998) |
| calmodulin-binding proteins | Proteins which bind calmodulin. They are found in many tissues and have a variety of functions including f-actin cross-linking properties, inhibition of cyclic nucleotide phosphodiesterase and calcium and magnesium atpases. (12 Dec 1998) |
| periplasmic binding proteins | Transport proteins located within the periplasmic space. Some act as receptors for bacterial chemotaxis, interacting with MCPs. Their mode of action is unclear. (18 Nov 1997) |
| RNA-binding proteins | Proteins which bind to RNA molecules. Certain structure motifs are common to several of the proteins, such as arginine (arg)-rich tracts, typically consisting of alternating arg-asp, arg-ser, or arg-gly residues. These proteins also tend to have a common ribonucleotide sequence domain. (12 Dec 1998) |
| DNA-binding proteins | Proteins which bind to DNA. The family includes proteins which bind to both double- and single-stranded DNA and also includes specific DNA binding proteins in serum which can be used as markers for malignant diseases. (12 Dec 1998) |
| insulin-like growth-factor-binding proteins | A family of soluble proteins that bind insulin-like growth factors and modulate their biological actions at the cellular level. (int j gynaecol obstet 1992;39(1):3-9) (12 Dec 1998) |
| thyroxine-binding proteins | A group of proteins that includes thyroxine-binding globulin, a glycoprotein that serves as the major and specific carrier of thyroxine in plasma, accounting for 70-75% of the bound thyroxine; thyroxine-binding prealbumin, an albumin that serves as the secondary carrier, accounting for between 20 and 25% of the bound thyroxine; and serum albumin, which accounts for the remaining bound thyroxine. (12 Dec 1998) |
| fatty acid binding proteins | <biochemistry> Group of small cytosolic proteins that bind fatty acids or other organic solutes. (18 Nov 1997) |
| acyl-CoA sterol acyltransferase | <enzyme> Isolated from saccharomyces cerevisiae; sat1 and sat2 are isoenzymes; genbank u55383 Registry number: EC 2.3.1- Synonym: sat1 gene product, sat2 gene product (26 Jun 1999) |
| gene regulatory protein | <molecular biology> Any protein that interacts with DNA sequences of a gene and controls its transcription. (18 Nov 1997) |
| region, regulatory | See: Regulatory sequence. (12 Dec 1998) |
| regulatory albuminuria | Transitory albuminuria occurring after unusual physical exertion. (05 Mar 2000) |
| regulatory cell proliferation kinase | <enzyme> Involved in mitosis regulation; has characteristics of serine/threonine and tyrosine kinases; isolated from saccharomyces cerevisiae; genbank l08909 Registry number: EC 2.7.1.- Synonym: rpk1 protein, rpk1 gene product (26 Jun 1999) |
| regulatory enzyme | <biochemistry> An enzyme that regulatescertain functions due to its ability to undergoa change in its catalytic activity through modification of its structure. (09 Oct 1997) |
