CC -!- FUNCTION: Promotes absorption of the essential vitamin cobalamin (Cbl) CC in the ileum. After interaction with CUBN, the CBLIF-cobalamin complex CC is internalized via receptor-mediated endocytosis (By similarity). CC {ECO:0000250}. CC -!- SUBUNIT: Interacts with CUBN (via CUB domains). {ECO:0000250}. CC -!- SUBCELLULAR LOCATION: Secreted. CC -!- TISSUE SPECIFICITY: Gastric mucosa. CC -!- SIMILARITY: Belongs to the eukaryotic cobalamin transport proteins CC family. {ECO:0000305}.
