Summary
Predicted to enable O-phospho-L-serine:2-oxoglutarate aminotransferase activity; identical protein binding activity; and pyridoxal phosphate binding activity. Predicted to be involved in L-serine biosynthetic process. Predicted to act upstream of or within cellular amino acid biosynthetic process. Predicted to be located in cytosol. Predicted to be active in cytoplasm. Is expressed in several structures, including alimentary system; genitourinary system; integumental system; nervous system; and sensory organ. Human ortholog(s) of this gene implicated in Neu-Laxova syndrome 2 and PSAT deficiency. Orthologous to human PSAT1 (phosphoserine aminotransferase 1).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
