Protein-coding gene in the species Homo sapiens
Phosphoserine aminotransferase (PSA) also known as phosphohydroxythreonine aminotransferase (PSAT) is an enzyme that in humans is encoded by the PSAT1 gene .[ 5]
The protein encoded by this gene is likely a phosphoserine aminotransferase , based on similarity to proteins in mouse, rabbit, and Drosophila . Alternative splicing of this gene results in two transcript variants encoding different isoforms .[ 5]
Clinical significance [ edit ] Homozygous or compound heterozygous mutations in PSAT1 cause Neu–Laxova syndrome [ 6] and phosphoserine aminotransferase deficiency.[ 7]
