Protein

Melanocyte-stimulating hormone receptor

Gene

MC1R

Organism
Canis lupus familiaris (Dog) (Canis familiaris)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Receptor for MSH (alpha, beta) and ACTH. Does not seem to be active with gamma-MSH. The activity of this receptor is mediated by G proteins which activate adenylate cyclase. Could be involved in spermatogenesis.

Interactioni

Subunit structurei

Interacts with MGRN1, but does not undergo MGRN1-mediated ubiquitination; this interaction competes with GNAS-binding and thus inhibits agonist-induced cAMP production.By similarity

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 one 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.
