Taxonomic identifier

4932 [NCBI]

Taxonomic lineage

Eukaryota › Fungi › Dikarya › Ascomycota › Saccharomycotina › Saccharomycetes › Saccharomycetales › Saccharomycetaceae › Saccharomyces

Protein attributes

Sequence length	760 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Serine/threonine haspin-like protein kinase involved in cell cycle regulation.
Catalytic activity	ATP + a protein = ADP + a phosphoprotein.
Induction	Absent in G1-arrested cells and accumulates in G2-M.
Domain	The KEN and D (destructive) boxes are required for the cell cycle-controled ALK1 degradation by the anaphase promoting complex (APC) pathway. The protein kinase domain is predicted to be catalytically inactive. However, weak kinase activity was experimentally demonstrated.
Post-translational modification	Periodically phosphorylated during the cell cycle with a phosphorylation peak during mitosis and hyperphosphorylated after DNA damage.
Miscellaneous	Present with 2190 molecules/cell in log phase SD medium.
Sequence similarities	Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. Haspin subfamily. Contains 1 protein kinase domain.
