Target

Full Name
Vaccinia Related Kinase 1
Function
Serine/threonine kinase involved in cell cycle, nuclear condensation and transcription regulation (PubMed:14645249, PubMed:18617507, PubMed:19103756).
Involved in Golgi disassembly during the cell cycle: following phosphorylation by PLK3 during mitosis, required to induce Golgi fragmentation (PubMed:19103756).
Phosphorylates 'Thr-18' of p53/TP53 and may thereby prevent the interaction between p53/TP53 and MDM2 (PubMed:10951572).
Phosphorylates KAT5 in response to DNA damage, promoting KAT5 association with chromatin and histone acetyltransferase activity (PubMed:33076429).
Phosphorylates BANF1: disrupts its ability to bind DNA, reduces its binding to LEM domain-containing proteins and causes its relocalization from the nucleus to the cytoplasm (PubMed:16495336).
Phosphorylates ATF2 which activates its transcriptional activity (PubMed:15105425).

Cellular Location
Nucleus
Cytoplasm
Dispersed throughout the cell but not located on mitotic spindle or chromatids during mitosis.
Involvement in disease
Pontocerebellar hypoplasia 1A (PCH1A):
A disorder characterized by an abnormally small cerebellum and brainstem, central and peripheral motor dysfunction from birth, gliosis and spinal cord anterior horn cells degeneration resembling infantile spinal muscular atrophy. Additional features include muscle hypotonia, congenital contractures and respiratory insufficiency that is evident at birth.
PTM
Autophosphorylated at various serine and threonine residues (PubMed:11883897, PubMed:14645249, PubMed:19103756, PubMed:21543316).
Autophosphorylation does not impair its ability to phosphorylate p53/TP53 (PubMed:11883897).
Phosphorylation by PLK3 leads to induction of Golgi fragmentation during mitosis (PubMed:19103756).
