SPTC3 rabbit pAb

The SPTLC3 gene encodes an isoform of the third subunit of serine palmitoyltransferase (SPT; EC 2. 3. 1. 50), which catalyzes the rate-limiting step of the de novo synthesis of sphingolipids (Hornemann et al. 2006 [PubMed 17023427]). SPT contains 2 main subunits: the common SPTLC1 subunit (MIM 605712) and either SPTLC2 (MIM 605713) or its isoform SPTLC2L (SPTLC3), depending on the tissue in which biosynthesis occurs (Hornemann et al. 2006 [PubMed 17023427]). There are also 2 highly related isoforms of a third subunit, SSSPTA (MIM 613540) and SSSPTB (MIM 610412), that confer acyl-CoA preference of the SPT enzyme and are essential for maximal enzyme activity (Han et al. 2009 [PubMed 19416851]).
