Lysosomal transporter that plays a role in the lysosomal release of vitamin B12 into the cytosol.

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.
