Functioni

Acts in vitro to stimulate the secretion of adrenocorticotropic hormone (ACTH) (By similarity). Binds with high affinity to CRF receptor types 1, 2-alpha, and 2-beta (By similarity). Plays a role in the establishment of normal hearing thresholds (PubMed:12091910). Reduces food intake and regulates ghrelin levels in gastric body and plasma (By similarity).By similarity1 Publication

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into Uniref entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
