IDBG-72636 (PSAT1)

Protein Structure

UniProt Annotation

Function

Catalyzes the reversible conversion of 3- phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4- phosphonooxybutanoate to phosphohydroxythreonine. {ECO:0000250}.

Subcellular Localization

Disease Associations

Phosphoserine aminotransferase deficiency (PSATD) [MIM:610992]: Characterized biochemically by low plasma and cerebrospinal fluid concentrations of serine and glycine and clinically by intractable seizures, acquired microcephaly, hypertonia, and psychomotor retardation. {ECO:0000269PubMed:17436247}. Note=The disease is caused by mutations affecting the gene represented in this entry.

Tissue Specificity

Expressed at high levels in the brain, liver, kidney and pancreas, and very weakly expressed in the thymus, prostate, testis and colon.
