This gene encodes a long chain base subunit of serine palmitoyltransferase. Serine palmitoyltransferase, which consists of two different subunits, is the key enzyme in sphingolipid biosynthesis. It catalyzes the pyridoxal-5-prime-phosphate-dependent condensation of L-serine and palmitoyl-CoA to 3-oxosphinganine. Mutations in this gene were identified in patients with hereditary sensory neuropathy type I. [provided by RefSeq, Mar 2011]
GeneCards Summary for SPTLC2 Gene
SPTLC2 (Serine Palmitoyltransferase Long Chain Base Subunit 2) is a Protein Coding gene. Diseases associated with SPTLC2 include Neuropathy, Hereditary Sensory And Autonomic, Type Ic and Dnmt1-Related Dementia, Deafness, And Sensory Neuropathy. Among its related pathways are Sphingolipid signaling pathway and Metabolism. GO annotations related to this gene include pyridoxal phosphate binding and serine C-palmitoyltransferase activity. An important paralog of this gene is SPTLC3.
UniProtKB/Swiss-Prot for SPTLC2 Gene
Serine palmitoyltransferase (SPT). The heterodimer formed with LCB1/SPTLC1 constitutes the catalytic core. The composition of the serine palmitoyltransferase (SPT) complex determines the substrate preference. The SPTLC1-SPTLC2-SPTSSA complex shows a strong preference for C16-CoA substrate, while the SPTLC1-SPTLC2-SPTSSB complex displays a preference for C18-CoA substrate.
