Ras-related protein Rab-38 is a protein that in humans is encoded by the RAB38 gene. On the basis of human genome sequence data, the RAB38 locus on chromosome 11 is flanked proximally by tyrosinase at 11q14-q21 and distally by EED at 11q14.2-q22.3 and MYO7A at 11q13.5. In melanocytic cells RAB38 gene expression may be regulated by MITF. May be involved in melanosomal transport and docking. Involved in the proper sorting of TYRP1.
