Full Name cubilin (intrinsic factor-cobalamin receptor)
Synonyms IFCR, MGA1, gp280
General protein information
Preferred Names
460 kDa receptor
cubilin precursor variant 1
cubilin precursor variant 2
intestinal intrinsic factor receptor
intrinsic factor-vitamin B12 receptor
Gene Type protein-coding
Organism Homo sapiens (human)



Summary Cubilin (CUBN) acts as a receptor for intrinsic factor-vitamin B12 complexes. The role of receptor is supported by the presence of 27 CUB domains. Cubulin is located within the epithelium of intestine and kidney. Mutations in CUBN may play a role in autosomal recessive megaloblastic anemia. [provided by RefSeq, Jul 2008].
