DBF2 kinase activator protein MOB1

UniProtKB accession:  P40484

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Functions as an activator subunit for the DBF2 protein kinase. Binds to DBF2, which is required for the phosphorylation and activation of DBF2 by the upstream kinase CDC15 in late anaphase. DBF2-MOB1 is part of the mitotic exit network (MEN) signaling cascade, which regulates release from the nucleus and activity of phosphatase CDC14. Required for inactivation of mitotic cyclin-dependent kinase for exit from mitosis, cytokinesis and G1 gene transcription.
