| Background Information | Phosphoserine aminotransferase (EC 2.6.1.52; UniProt Q9Y617; also known as Phosphohydroxythreonine aminotransferase, PSAT) is encoded by the PSAT1 (also known as NLS2, PSA, PSATD) gene (Gene ID 29968) in human. PSAT1 is a class-V pyridoxal-phosphate-dependent aminotransferase family member that catalyzes the reversible conversion of 3-phosphohydroxypyruvate and to 1-phosphoserine, as well as the conversion of 3-hydroxy-2-oxo-4-phosphonooxybutanoate to 4-phosphonooxy-L-threonine, using, in both cases, L-glutamate as an amine donor, which is converted to 2-oxoglutarate. PSAT1 is involved in serine biosynthesis from glycolytic intermediates and PSAT1 upregulation is reported in non-small cell lung cancer (NSCLC) and colon cancer cells, while PSAT1 knockdoown is shown to suppress the proliferation of MDA-MB-468 and BT-20 breast cancer cells. |
