Anti-SPTLC1 Antibody

半岛bd体育手机客户端 说明

一般描述

Serine palmitoyltransferase 1 (EC 2.3.1.50; UniProt O15269; also known as LCB 1, Long chain base biosynthesis protein 1, Serine-palmitoyl-CoA transferase 1, SPT 1, SPT1) is encoded by the SPTLC1 (also known as HSAN1, HSAN1A, LCB1) gene (Gene ID 10558) in human. Serine palmitoyltransferase (SPT) catalyzes pyridoxal 5-phosphate-/PLP-dependent condensation of L-serine with palmitoyl-CoA to generate 3-ketodihydrosphingosine, the rate-limiting step for the de novo synthesis of sphingolipids. SPT belongs to the POAS (PLP-dependent α-oxoamine synthase) family of enzymes, members of this family also include 5-amino-levulinic acid synthase, KBL (2-amino-3 ketobutyrate ligase) and AONS (8-amino-7-oxononanoate synthase). Unlike the other known POAS family members that all exist as soluble homodimers, SPT is bound to the outer membrane of the endoplasmic reticulum (ER) as a multisubunit complex composed of three distinct subunits, SPTLC1, SPTLC2 and SPTLC3. SPTLC1 is a 473-amino acid sigle-transmembrane (a.a. 16-36) protein with a short N-terminal lumenal domain (a.a. 1-15) and a large C-terminal cytoplasmic domain (a.a. 37-473). Alternative splicing generates an isoform with a truncated cytoplasmic domain (D143 switched to E143, a.a. 144-473 truncated).

特异性

Expected to react with both spliced isoforms of human Serine palmitoyltransferase 1/SPTLC1 reported by UniProt (O15269).

免疫原

Epitope: Cytoplasmic domain.
Two linear peptides corresponding to sequences from the N- and a C-terminal regions of human SPTLC1 cytoplasmic domain.

应用

Anti-SPTLC1 Antibody is an antibody against SPTLC1 for use in Western Blotting.
Western Blotting Analysis: The purified polyclonal antibody was used to detect the presence of SPTLC1 in SPTLC2 and SPTLC3 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 SPTLC1 in human cell lysates (HEK293, HepG2, JAR, JEG3) and human placenta tissue homogenate (Hornemann, T., et al. (2006). J. Biol. Chem. 281(49):37275-37281).
