Proprotein convertase 2 (PC2) also known as prohormone convertase 2 or neuroendocrine convertase 2 (NEC2) is a serine protease and proprotein convertase PC2, like proprotein convertase 1 (PC1), is an enzyme responsible for the first step in the maturation of many neuroendocrine peptides from their precursors, such as the conversion of proinsulin to insulin intermediates.
Proprotein convertase 1, also known as prohormone convertase, prohormone convertase 3, or neuroendocrine convertase 1 and often abbreviated as PC1/3 is an enzyme that in humans is encoded by the PCSK1 gene. [5] PCSK1 and PCSK2 differentially cleave proopiomelanocortin and they act together to process proinsulin and proglucagon in pancreatic ...
Progesterone (/ p r oʊ ˈ dʒ ɛ s t ər oʊ n / ⓘ; P4) is an endogenous steroid and progestogen sex hormone involved in the menstrual cycle, pregnancy, and embryogenesis of humans and other species.
N-terminal prohormone of brain natriuretic peptide (NT-proBNP or BNPT) is a 76 amino acid long protein that is cleaved from the N-terminal end of the 108 amino acid long prohormone proBNP to release brain natriuretic peptide 32 (BNP, also known as B-type natriuretic peptide). [1] [2] [3] [4]
An androgen prohormone, or proandrogen, is a prohormone (or prodrug) of an anabolic-androgenic steroid (AAS). They can be prohormones of testosterone or of synthetic AAS, for example, nandrolone (19-nortestosterone). Dehydroepiandrosterone (DHEA), DHEA sulfate (DHEA-S), and androstenedione may all be considered proandrogens of testosterone. [1]
Kexin (EC 3.4.21.61) is a prohormone-processing protease, specifically a yeast serine peptidase, [1] found in the budding yeast (S. cerevisiae). It catalyzes the cleavage of -Lys-Arg- and -Arg-Arg- bonds to process yeast alpha-factor pheromone and killer toxin precursors. The human homolog is PCSK4. It is a family of subtilisin-like peptidases.
1-Androstenediol, or 5α-androst-1-ene-3β,17β-diol, also known as 4,5α-dihydro-δ 1-4-androstenediol, is a prohormone of 1-testosterone (Δ 1-DHT). [ 1 ] [ 2 ] It has been used as a dietary supplement , and is identified by the World Anti-Doping Agency as a prohibited substance related to anabolic steroids .
In 2001 Arnold's company introduced the prohormone 1-Androstenediol, under the marketing name 1-AD. Like andro, 1-AD is a prohormone that is easily converted by the body into 1-testosterone, and it sold well. But the boom was short-lived. In January '05 an amendment to the federal Controlled Substance Act banned prohormones. The company lost 60 ...
