Anti-SPTLC1 antibody,Abcam,AB176706

Target data Component of the serine palmitoyltransferase multisubunit enzyme (SPT) that catalyzes the initial and rate-limiting step in sphingolipid biosynthesis by condensing L-serine and activated acyl-CoA (most commonly palmitoyl-CoA) to form long-chain bases. The SPT complex is also composed of SPTLC2 or SPTLC3 and SPTSSA or SPTSSB. Within this complex, the heterodimer with SPTLC2 or SPTLC3 forms the catalytic core (PubMed : 19416851, PubMed : 33558762, PubMed : 36170811). The composition of the serine palmitoyltransferase (SPT) complex determines the substrate preference (PubMed : 19416851, PubMed : 33558762). The SPTLC1-SPTLC2-SPTSSA complex shows a strong preference for C16-CoA substrate, while the SPTLC1-SPTLC3-SPTSSA isozyme uses both C14-CoA and C16-CoA as substrates, with a slight preference for C14-CoA (PubMed : 19416851, PubMed : 19648650). The SPTLC1-SPTLC2-SPTSSB complex shows a strong preference for C18-CoA substrate, while the SPTLC1-SPTLC3-SPTSSB isozyme displays an ability to use a broader range of acyl-CoAs, without apparent preference (PubMed : 19416851, PubMed : 19648650, PubMed : 33558761, PubMed : 33558762). Required for adipocyte cell viability and metabolic homeostasis (By similarity). See full target information SPTLC1
