Cholesterol-binding protein involved in the redistribution of cholesterol from lipid droplets to the endoplasmic reticulum . Required to meet cholesterol demands during erythropoietic differentiation . May play a role in transport processes at the plasma membrane of erythrocytes, including regulating VDAC-mediated ATP export, and import of the heme precursors protoporphyrin IX and 5-aminolevulinic acid ( ).
Subcellular locations: Endoplasmic reticulum membrane, Cell membrane
Localizes to the plasma membrane and intracellular membranes in developing and mature erythrocytes.
Expressed in erythrocytes (at protein level).
