| 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. May play a role in signal transduction. {ECO:0000269|PubMed:19416851}.

| Subcellular Location |
Endoplasmic reticulum membrane {ECO:0000305}; Multi-pass membrane protein {ECO:0000305}.
|
| Tissue Specificity |
Expression is seen predominantly in the prostate epithelium with weaker expression in the fibroblasts and endothelial cells. {ECO:0000269|PubMed:15777716}.
