Protein

Serine/threonine-protein kinase Nek4

Gene

NEK4

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Protein kinase that seems to act exclusively upon threonine residues (By similarity). Required for normal entry into proliferative arrest after a limited number of cell divisions, also called replicative senescence. Required for normal cell cycle arrest in response to double-stranded DNA damage.By similarity1 Publication

Catalytic activityi

ATP + a protein = ADP + a phosphoprotein.By similarity

Cofactori
