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] Expression Ubiquitous expression in spleen (RPKM 26.7), colon (RPKM 20.1) and 25 other tissues See more Orthologs mouse all
