SPTLC1 - serine palmitoyltransferase long chain base subunit 1 Gene
Also Known as HSN1; LBC1; LCB1; SPT1; SPTI; HSAN1
Species: Homo sapiens
About SPTLC1
This gene has 25 transcripts (splice variants), 205 orthologues, 5 paralogues and is associated with 3 phenotypes. Ubiquitous expression in thyroid (RPKM 21.8), esophagus (RPKM 19.8) and 25 other tissues.
Summary
This gene encodes a member of the class-II pyridoxal-phosphate-dependent aminotransferase family. The encoded protein is the long chain base subunit 1 of serine palmitoyltransferase. Serine palmitoyltransferase converts L-serine and palmitoyl-CoA to 3-oxosphinganine with pyridoxal 5'-phosphate and is the key enzyme in sphingolipid biosynthesis. Mutations in this gene were identified in patients with hereditary sensory neuropathy type 1. Alternatively spliced variants encoding different isoforms have been identified. Pseudogenes of this gene have been defined on chromosomes 1, 6, 10, and 13. [provided by RefSeq, Jul 2013]
