Protein attributes

Sequence length	313 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Activated during M phase. Required for chromosome segregation at metaphase-anaphase transition and therefore for mitotic progression. Inhibition of activity results in apoptosis. Ref.2 Ref.9
Catalytic activity	ATP + a protein = ADP + a phosphoprotein.
Cofactor	Magnesium.
Subcellular location	Cytoplasm. Nucleus. Ref.2
Tissue specificity	Ubiquitous, with highest expression in heart and skeletal muscle. Ref.2
Post-translational modification	Autophosphorylated. Ref.9
Sequence similarities	Belongs to the protein kinase superfamily. NEK Ser/Thr protein kinase family. NIMA subfamily. Contains 1 protein kinase domain.
Sequence caution	The sequence CAH70247.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence CAI10876.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence EAW87581.1 differs from that shown. Reason: Erroneous gene model prediction.
