Background InformationSerine palmitoyltransferase 3 (EC 2.3.1.50; UniProt Q9NUV7; also known as LCB 3, LCB2b, Long chain base biosynthesis protein 2b, Long chain base biosynthesis protein 3, Serine-palmitoyl-CoA transferase 3, SPT 3) is encoded by the SPTLC3 (also known as C20orf38, SPTLC2L) gene (Gene ID 55304) in human. Serine palmitoyltransferase (SPT) is a pyridoxal 5'-phosphate (PLP)-dependent enzyme that catalyses the first step of de novo sphingolipids (SLs) biosynthesis, namely the condensation of L-serine with palmitoyl coenzyme-A to generate 3-ketodehydrosphinganine (KDS) that forms the sphingoid base backbone of all SLs. The core human SPT homoenzyme is a membrane-bound heterodimer composed of an hLCB1 (SPTLC1) subunit together with either an hLCB2a (SPTLC2) or an hLCB2b (SPTLC3) subunit. The hLCB1/hLCB2 heterodimer contains a single active site composed of residues from both subunits. hLCB2a and hLCB2b share 68% sequence identity, with hLCB2b being the isotype that is predominantly expressed in the placenta and prefers shorter chain acyl-CoAs (C12 and C14) to generate short-chain SLs. In addition, two human small subunits (ssSPTa and ssSPTb) have been identified and found to maximize the catalytic activity and to confer the acyl-CoA substrate chain-length specificity of the hLCB1/hLCB2 core enzyme. Mutations in hLCB1 and hLCB2a are found in patients with hereditary sensory and autonomic neuropathy type I (HSAN1), an inherited disorder that affects sensory and autonomic neurons due to neurotoxic deoxysphingolipids formation as a result of substrate promiscuity of the mutated SPT enzyme.

Key Applications
  • Western Blotting
Application NotesWestern Blotting Analysis: The purified polyclonal antibody was used to detect the presence of SPTLC2 in SPTLC1 and SPTLC2 immunoprecipiates from human placenta tissue homogenate (Hornemann, T., et al. (2007). Biochem. J. 405(1):157-164).

Western Blotting Analysis: The purified polyclonal antibody was used to detect the endogenous SPTLC3 in human cell lysates (HepG2, JAR, JEG3) and human placenta tissue homogenate, as well as exogenously expressed SPTLC3 in transfected HEK293 cells (Hornemann, T., et al. (2007). Biochem. J. 405(1):157-164; Hornemann, T., et al. (2006). J. Biol. Chem. 281(49):37275-37281).
Biological Information
ImmunogenA mixture of two linear peptides corresponding to sequences near the N- and C-terminal ends of human SPTLC3.

SpecificityTarget-specificity of this antiserum was verified by negative blotting using pre-immune serum and by target band blocking using immunogen peptides (Hornemann, T., et al. (2006). J. Biol. Chem. 281(49):37275-37281). Expected to react with both spliced isoforms of human Serine palmitoyltransferase 3/SPTLC3 reported by UniProt (Q9NUV7).

Molecular Weight~52 kDa observed. 62.05 kDa (isoform 1) and 19.63 kDa (isoform 2) calculated. The smaller-than-calculated band size is consistent with that reported in the literature (Hornemann, T., et al. (2007). Biochem. J. 405(1):157-164; Hornemann, T., et al. (2006). J. Biol. Chem. 281(49):37275-37281). Uncharacterized bands may be observed in some lysate(s).
