Entrez Gene Summary for GPR143 Gene

  • This gene encodes a protein that binds to heterotrimeric G proteins and is targeted to melanosomes in pigment cells. This protein is thought to be involved in intracellular signal transduction mechanisms. Mutations in this gene cause ocular albinism type 1, also referred to as Nettleship-Falls type ocular albinism, a severe visual disorder. A related pseudogene has been identified on chromosome Y. [provided by RefSeq, Dec 2009]

GeneCards Summary for GPR143 Gene

GPR143 (G Protein-Coupled Receptor 143) is a Protein Coding gene. Diseases associated with GPR143 include ocular albinism, x-linked and nystagmus 6, congenital, x-linked. Among its related pathways are GPCRs, Other. GO annotations related to this gene include G-protein coupled receptor activity and tyrosine binding.

UniProtKB/Swiss-Prot for GPR143 Gene

  • Receptor for tyrosine, L-DOPA and dopamine. After binding to L-DOPA, stimulates Ca(2+) 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.

  • Albinism ocular 1 (OA1) [MIM:300500]: Form 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. {ECO:0000269 PubMed:11214907, ECO:0000269 PubMed:16646960, ECO:0000269 PubMed:17822861, ECO:0000269 PubMed:17960122, ECO:0000269 PubMed:18978956, ECO:0000269 PubMed:8634705, ECO:0000269 PubMed:9529334, ECO:0000269 PubMed:9887374}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Nystagmus congenital X-linked 6 (NYS6) [MIM:300814]: A condition defined as conjugated, spontaneous and involuntary ocular oscillations that appear at birth or during the first three months of life. Other associated features may include mildly decreased visual acuity, strabismus, astigmatism, and occasionally head nodding. {ECO:0000269 PubMed:17516023}. Note=The disease is caused by mutations affecting the gene represented in this entry.
