| receptors, pituitary hormone-regulating hormone | Cell surface receptors that bind the hypothalamic hormones regulating pituitary cell differentiation, proliferation, and hormone synthesis and release, including the pituitary-releasing and release-inhibiting hormones. The pituitary hormone-regulating hormones are also released by cells other than hypothalamic neurons, and their receptors also occur on non-pituitary cells, especially brain neurons, where their role is less well understood. Receptors for dopamine, which is a prolactin release-inhibiting hormone as well as a common neurotransmitter, are not included here. (12 Dec 1998) |
|---|---|
| growth hormone inhibiting hormone | <protein> Gastrointestinal and hypothalmic peptide hormone (two forms: 14 and 28 residues), found in gastric mucosa, pancreatic islets, nerves of the gastrointestinal tract, in posterior pituitary and in the central nervous system. Inhibits gastric secretion and motility: in hypothalamus/pituitary inhibits somatotropin release. (18 Nov 1997) |
| growth hormone-regulating hormone | <endocrinology> Hypothalamic hormones that induce (somatoliberin) or inhibit (somatostatin) the release of growth hormone (somatotropin). (18 Nov 1997) |
| growth hormone-releasing hormone | <endocrinology> Peptide hormone related to the glucagon family, released from the pituitary, acts on the adenohypophysis to release growth hormone. Synonym: somatoliberin, growth hormone-releasing factor. (20 Sep 2002) |
| hormones, hormone substitutes, and hormone antagonists | A collective grouping for both naturally occurring and synthetic hormones, substitutes, and antagonists. (12 Dec 1998) |
| follicle-stimulating hormone-releasing hormone | A decapeptide of hypothalamic origin capable of accelerating pituitary secretion of follitropin. Synonym: follicle-stimulating hormone-releasing factor, follicle-stimulating hormone-releasing hormone. Origin: follicle-stimulating hormone + L. Libero, to free, + -in (05 Mar 2000) |
| luteinizing hormone/follicle-stimulating hormone-releasing factor | gonadotrophin-releasing hormone |
| luteinizing hormone-releasing hormone | A hormone that controls sex hormones in men and women. Also called lhrh. (12 Dec 1998) |
| 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) |
| viral regulatory proteins | Proteins which regulate the rate of transcription of viral structural genes. (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) |
| regulatory gene | A gene that codes for a repressor protein. (09 Oct 1997) |
