Cerebellin is a 16-amino acid peptide originally isolated from rat cerebellum, which actually comes from precerebellin (cerebellin-1) processing into cerebellin and [des-Ser1]-cerebellin. Cerebellin is widely distributed in the central nervous system, where it exerts neuromodulatory functions by directly stimulating norepinephrine release via the adenylate cyclase/PKA-dependent signaling pathway; and indirectly enhances adrenocortical secretion in vivo, through a paracrine mechanism involving medullary catecholamine release.Human: H-Ser-Gly-Ser-Ala-Lys-Val-Ala-Phe-Ser-Ala-Ile-Arg-Ser-Thr-Asn-His-OH or H-SGSAKVAFSAIRSTNH-OH
