"OCA2" - P protein in Homo sapiens
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
some 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

OCA2P protein; Could be involved in the transport of tyrosine, the precursor to melanin synthesis, within the melanocyte. Regulates the pH of melanosome and the melanosome maturation. One of the components of the mammalian pigmentary system. Seems to regulate the post-translational processing of tyrosinase, which catalyzes the limiting reaction in melanin synthesis. May serve as a key control point at which ethnic skin color variation is determined. Major determinant of brown and/or blue eye color; Belongs to the CitM (TC 2.A.11) transporter family (838 aa)    
Predicted Functional Partners:
TYR
Tyrosinase; This is a copper-containing oxidase that functions in the formation of pigments such as melanins and other polyphenolic compounds. Catalyzes the initial and rate limiting step in the cascade of reactions leading to melanin production from tyrosine. In addition to hydroxylating tyrosine to DOPA (3,4- dihydroxyphenylalanine), also catalyzes the oxidation of DOPA to DOPA-quinone, and possibly the oxidation of DHI (5,6- dihydroxyindole) to indole-5,6 quinone; Belongs to the tyrosinase family (529 aa)
     
   
  0.934
SLC24A5
Sodium/potassium/calcium exchanger 5; Cation exchanger involved in pigmentation, possibly by participating in ion transport in melanosomes. Predominant sodium- Calcium exchanger in melanocytes. Probably transports 1 Ca(2+) and 1 K(+) to the melanosome in exchange for 4 cytoplasmic Na(+); Belongs to the Ca(2+)-cation antiporter (CaCA) (TC 2.A.19) family. SLC24A subfamily (500 aa)
   
   
  0.930
SLC45A2
Membrane-associated transporter protein; Melanocyte differentiation antigen. May transport substances required for melanin biosynthesis (By similarity); Belongs to the glycoside-pentoside-hexuronide (GPH) cation symporter transporter (TC 2.A.2) family (530 aa)
     
   
  0.930
TYRP1
5,6-dihydroxyindole-2-carboxylic acid oxidase; Catalyzes the oxidation of 5,6-dihydroxyindole-2- carboxylic acid (DHICA) into indole-5,6-quinone-2-carboxylic acid in the presence of bound Cu(2+) ions. May regulate or influence the type of melanin synthesized. Also to a lower extent, capable of hydroxylating tyrosine and producing melanin (By similarity) (537 aa)
     
   
  0.856
MC1R
Melanocyte-stimulating hormone receptor; Receptor for MSH (alpha, beta and gamma) and ACTH. The activity of this receptor is mediated by G proteins which activate adenylate cyclase; Belongs to the G-protein coupled receptor 1 family (317 aa)
     
   
  0.825
GLDC
Glycine dehydrogenase (decarboxylating), mitochondrial; The glycine cleavage system catalyzes the degradation of glycine. The P protein (GLDC) binds the alpha-amino group of glycine through its pyridoxal phosphate cofactor; CO(2) is released and the remaining methylamine moiety is then transferred to the lipoamide cofactor of the H protein (GCSH) (1020 aa)
     
   
  0.806
AMT
Aminomethyltransferase, mitochondrial; The glycine cleavage system catalyzes the degradation of glycine (403 aa)
     
   
  0.806
GCSH
Glycine cleavage system H protein, mitochondrial; The glycine cleavage system catalyzes the degradation of glycine. The H protein (GCSH) shuttles the methylamine group of glycine from the P protein (GLDC) to the T protein (GCST); Belongs to the GcvH family (173 aa)
     
   
  0.767
SLC24A4
Sodium/potassium/calcium exchanger 4; Transports 1 Ca(2+) and 1 K(+) in exchange for 4 Na(+). Controls the rapid response termination and proper regulation of adaptation in olfactory sensory neurons (OSNs) which subsequently influences how odor information is encoded and perceived. May play a role in calcium transport during amelogenesis (By similarity); Belongs to the Ca(2+)-cation antiporter (CaCA) (TC 2.A.19) family. SLC24A subfamily (622 aa)
   
   
  0.716
MYBPH
Myosin-binding protein H; Binds to myosin; probably involved in interaction with thick myofilaments in the A-band; Fibronectin type III domain containing (477 aa)
