MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Serine palmitoyltransferase (SPT; EC catalyzes the first committed and rate-limiting step in sphingolipid biosynthesis. SSSPTB is a small SPT subunit that stimulates SPT activity and confers acyl-CoA preference to the SPT catalytic heterodimer of SPTLC1 (MIM 605712) and either SPTLC2 (MIM 605713) or SPTLC3 (MIM 611120) (Han et al., 2009 [PubMed 19416851]).[supplied by OMIM, Nov 2010]
PHENOTYPE: Mice heterozygous for an ENU mutation exhibit shiny flecks in the ocular fundus and brain vacuoles. Mice homozygous for the allele exhibit premature death, ataxia, decreased weight, shiny flecks in the ocular fundus, brain and retina vacuoles and impaired ER stress response.
