Function | Lysosomal membrane protein that transports cobalamin (Vitamin B12) from the lysosomal lumen to the cytosol in an ATP-dependent manner. Targeted by LMBRD1 lysosomal chaperone from the endoplasmic reticulum to the lysosomal membrane. Then forms a complex with lysosomal chaperone LMBRD1 and cytosolic MMACHC to transport cobalamin across the lysosomal membrane. |
