CRFR
Corticotropin-releasing Factor Receptor; CRHR
The CRFR (Corticotropin-releasing Factor Receptor, CRHR) belongs to the G-coupled receptor superfamily. Two receptor subtypes, CRF1 receptor and CRF2 receptor, and several splice variants for both receptor subtypes have been discovered. CRF itself has a greater affinity for CRF1 receptors while urocortin 1 (Ucn 1) binds with high affinity to both receptors and Ucn 2 and Ucn 3 both preferentially bind to CRF2 receptors.
Two CRF receptor subtypes are encoded by distinct genes which exhibit diverse alternative pre-mRNA splicing patterns resulting in multiple variants derived from partial or total exon deletions or insertions. With regard to the nine human CRF1 variants, CRF1a-i, described, CRF1a being the main wild type functional receptor while the other isoforms may modulate CRF signaling. For the CRF2, three functionally active splice variants, CRF2a-c, have been described in humans.

Tetracosactide acetate
0 ImagesSynonyms: Tetracosactrin acetate; ACTH(1–24) acetateTetracosactide acetate (Tetracosactrin acetate ) is the acetate salt form of Tetracosactide (HY-P0060). Tetracosactide acetate is an analogue of adrenocorticotrophic hormone (ACTH). Tetracosactide acetate is the agonist for melanocortin-4 receptor (MC4R) that activates human MC4R with an EC50 of 0.65 nM. Tetracosactide acetate can stimulate the release of corticosteroids such as cortisol from the adrenal gland. Tetracosactide acetate is currently used for the research of ulcerative colitis and Crohn's disease, juvenile/adult rheumatoid arthritis and osteoarthrosis.
