MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of the vitamin B12-binding protein family. This family of proteins, alternatively referred to as R binders, is expressed in various tissues and secretions. This plasma protein binds cobalamin and mediates the transport of cobalamin into cells. This protein and other mammalian cobalamin-binding proteins, such as transcobalamin I and gastric intrisic factor, may have evolved by duplication of a common ancestral gene. Alternative splicing results in multiple transcript variants.[provided by RefSeq, May 2010]
PHENOTYPE: This locus controls transcobalamin-2 electrophoretic variation. The s allele determines a slow band in serum from A/J, C57BL/6, BALB/c and C3H/He; the f allele determines faster form in NZB, ST/b and CPB-WV. Heterozygotes have both forms. Sequencing reveals a Gly to Glu substitution in NZB compared to BALB/c, DBA/2 and C57BL/6 (Genbank AF090686). [provided by MGI curators]
