  • Function

    Serine/threonine kinase that phosphorylates 'Thr-18' of p53/TP53 and may thereby prevent the interaction between p53/TP53 and MDM2.
  • Tissue specificity

    Widely expressed. Highly expressed in fetal liver, testis and thymus.
  • Involvement in disease

    Defects in VRK1 are the cause of pontocerebellar hypoplasia type 1 (PCH1) [MIM:607596]; also called pontocerebellar hypoplasia with infantile spinal muscular atrophy or pontocerebellar hypoplasia with anterior horn cell disease. PCH1 is characterized by an abnormally small cerebellum and brainstem, central and peripheral motor dysfunction from birth, gliosis and anterior horn cell degeneration resembling infantile spinal muscular atrophy (SMA).
  • Sequence similarities

    Belongs to the protein kinase superfamily. CK1 Ser/Thr protein kinase family. VRK subfamily.
    Contains 1 protein kinase domain.
  • Post-translational
    modifications

    Autophosphorylated at various serine and threonine residues. Autophosphorylation does not impair its ability to phosphorylate p53/TP53.
  • Cellular localization

    Nucleus. Dispersed throughout the cell but not located on mitotic spindle or chromatids during mitosis.
  • Information by UniProt
