Functioni

Receptor for tyrosine, L-DOPA and dopamine. After binding to L-DOPA, stimulates Ca2+ influx into the cytoplasm, increases secretion of the neurotrophic factor SERPINF1 and relocalizes beta arrestin at the plasma membrane; this ligand-dependent signaling occurs through a G(q)-mediated pathway in melanocytic cells. Its activity is mediated by G proteins which activate the phosphoinositide signaling pathway. Plays also a role as an intracellular G protein-coupled receptor involved in melanosome biogenesis, organization and transport.5 Publications

Albinism ocular 1 (OA1)8 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionForm of albinism affecting only the eye. Pigment of the hair and skin is normal or only slightly diluted. Eyes may be severely affected with photophobia and reduced visual acuity. Nystagmus or strabismus are often associated. The irides and fundus are depigmented.

Similar proteinsi

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.
