Constitutive expression of murine Sak-a suppresses cell growth and induces multinucleation.

The murine Sak gene encodes two isoforms of a putative serine/threonine kinase, Sak-a and Sak-b, with a common N-terminal kinase domain and different C-terminal sequences. Sak is expressed primarily at sites where cell division is most active in adult and embryonic tissues (C. Fode, B. Motro, S. Youseli, M. Heffernan, and J. W. Dennis, Proc. Natl. Acad.
