PSAT1
Phosphoserine aminotransferase also known as phosphohydroxythreonine aminotransferase is an enzyme that in humans is encoded by the PSAT1 gene.
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.
