MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Gangliosides are membrane-bound glycosphingolipids containing sialic acid. Ganglioside GD3 is known to be important for cell adhesion and growth of cultured malignant cells. The protein encoded by this gene is a type II membrane protein that catalyzes the transfer of sialic acid from CMP-sialic acid to GM3 to produce gangliosides GD3 and GT3. The encoded protein may be found in the Golgi apparatus and is a member of glycosyltransferase family 29. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jan 2015]
PHENOTYPE: Homozygotes for a targeted allele are behaviorally normal with no signs of aberrant brain histology or demyelination. Homozygotes for a knock-out allele are behaviorally intact with normal nervous tissue morphology and sensitivity to Fas-mediated apoptosis but show impaired repair of damaged nerves.
