MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes the transcobalamin receptor that is expressed at the cell surface. It mediates the cellular uptake of transcobalamin bound cobalamin (vitamin B12), and is involved in B-cell proliferation and immunoglobulin secretion. Mutations in this gene are associated with methylmalonic aciduria. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jan 2011]
PHENOTYPE: The homozygous mutant and heterozygous mice exhibited an increased mean retinal artery-to-vein ratio when compared with controls. Mice homozygous for a gene trap knock-out allele exhibit vitamin B12 deficiency in the central nervous system. [provided by MGI curators]
