serine palmitoyltransferase small subunit B [Homo sapiens]

Protein Classification

serine palmitoyltransferase small subunit family protein( domain architecture ID 10570340)

serine palmitoyltransferase small subunit (SPTSS) family protein such as SPTSS that stimulates the activity of serine palmitoyltransferase (SPT); the composition of the SPT complex determines substrate preference

 7-60 1.34e-13

Small subunit of serine palmitoyltransferase-like; Serine palmitoyltransferase (SPT) catalyzes the first committed step in sphingolipid biosynthesis. In mammals, two small subunits of serine palmitoyltransferase, ssSPTa and ssSPTb, substantially enhance the activity of SPT, conferring full enzyme activity upon it. The 2 ssSPT isoforms share a conserved hydrophobic central domain, which is predicted to reside in the membrane.
