Protein Structure
UniProt Annotation
Function Stimulates the activity of serine palmitoyltransferase (SPT). The composition of the serine palmitoyltransferase (SPT) complex determines the substrate preference, complexes with this subunit showing a clear preference for longer acyl-CoAs. 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 (By similarity). {ECO:0000250}.
Subcellular Localization Endoplasmic reticulum membrane {ECO:0000305}; Multi-pass membrane protein {ECO:0000305}.
Disease Associations
Tissue Specificity Expression is strong in hypogonadal (hpg) mouse prostate, weak in mature castrated mouse prostate and absent in normal intact or androgen-replaced hpg mouse prostates. {ECO:0000269PubMed:15777716}.
