FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a type II transmembrane protein that is similar to the core 1 beta1,3-galactosyltransferase 1, which catalyzes the synthesis of the core-1 structure, also known as Thomsen-Friedenreich antigen, on O-linked glycans. This gene product lacks the galactosyltransferase activity itself, but instead acts as a molecular chaperone required for the folding, stability and full activity of the core 1 beta1,3-galactosyltransferase 1. Mutations in this gene have been associated with Tn syndrome. Alternatively spliced transcript variants encoding the same protein have been identified. [provided by RefSeq, Dec 2009]
PHENOTYPE: Male mice hemizygous for a knock-out allele exhibit embryonic lethality with hemorrhaging. Female mice heterozygous for a knock-out allele exhibit some embryonic lethality with hemorrhage and disorganized vascular system and surviving mice dieing postnatally. [provided by MGI curators]
