Phosphoserine phosphatase is an enzyme that in humans is encoded by the PSPH gene.[1][2][3]

Function

The protein encoded by this gene belongs to a subfamily of the phosphotransferases. This encoded enzyme is responsible for the third and last step in L-serine formation. It catalyzes magnesium-dependent hydrolysis of L-phosphoserine and is also involved in an exchange reaction between L-serine and L-phosphoserine. Deficiency of this protein is thought to be linked to Williams syndrome.[3]

Clinical significance

Homozygous or compound heterozygous mutations in PSPH cause Neu-Laxova syndrome[4] and Phosphoserine phosphatase deficiency.[5][6]

Model organisms

Model organisms have been used in the study of PSPH function. A conditional knockout mouse line called Psphtm1a(EUCOMM)Hmgu was generated at the Wellcome Trust Sanger Institute.[7] Male and female animals underwent a standardized phenotypic screen[8] to determine the effects of deletion.[9][10][11][12] Additional screens performed: - In-depth immunological phenotyping[13]
