PRA1 Domain Family, Member 2 (PRAF2)


PRA1 Domain Family, Member 2 (PRAF2)
PRA1 domain family, member 2 (PRAF2) is a new 19 kDa protein with four putative transmembrane (TM) domains. PRAF2 (formerly designated JM4) belongs to a new protein family, which plays a role in the regulation of intracellular protein transport. Recently, PRAF2 was found to interact with the chemokine receptor CCR5. PRAF2 encodes a 178-residue protein, whose sequence is related to PRAF1 (PRA1/prenylin) and PRAF3 (JWA/GTRAP3-18). The human PRAF2 gene contains three exons separated by two introns and is located on human chromosome Xp11.23. The recombinant PRAF2 protein was readily expressed in Schneider 2 (S2) insect cells, and the native protein was detected in human tissues with strong expression in the brain, small intestine, lung, spleen, and pancreas. The protein was undetectable in tissue of the testes.
