Membrane-associated transporter protein (MATP) also known as solute carrier family 45 member 2 (SLC45A2) or melanoma antigen AIM1 is a protein that in humans is encoded by the SLC45A2 gene.[1][2][3]

In human, the SLC45A2 gene is located on the short (p) arm of chromosome 5 at position 13.2.

Function

SLC45A2 is a transporter protein that mediates melanin synthesis. SLC45A2 is also a melanocyte differentiation antigen that is expressed in a high percentage of melanoma cell lines.[4] A similar sequence gene in medaka fish, 'B,' encodes a transporter that mediates melanin synthesis. Mutations in this gene are a cause of oculocutaneous albinism type 4. Alternative splicing results in multiple transcript variants encoding different isoforms.[3]

In melanocytic cell types, the SLC45A2 gene is regulated by microphthalmia-associated transcription factor.[5][6]

SLC45A2 has been found to play a role in pigmentation in several species. In humans, it has been identified as a factor in the light skin of Europeans and as an ancestry-informative marker (AIM) for distinguishing Sri Lankan from European ancestry.[7] SLC45A2 is the so-called cream gene responsible in horses for buckskin, palomino and cremello coloration, while a mutation in this gene underlies the white tiger variant.[8] SLC45A2 was identified as a melanoma tumor-associated antigen with high tumor specificity and reduced potential for autoimmune toxicity, and is currently in clinical development as a target for T-cell based immunotherapy.[9]
