Involved in the transport of proteins between the endosomes and the trans Golgi network. Involved in the recruitment of SGSM2 to melanosomes and is required for the proper trafficking of melanogenic enzymes TYR, TYRP1 and DCT/TYRP2 to melanosomes in melanocytes.
Subcellular locations: Cell membrane, Endoplasmic reticulum membrane, Golgi apparatus membrane, Late endosome, Cytoplasmic vesicle, Phagosome membrane, Cytoplasmic vesicle, Phagosome, Cytoplasmic vesicle membrane, Melanosome
Colocalizes with OSBPL1A at the late endosome . Recruited to phagosomes containing S.aureus or M.tuberculosis .
