Protein JTB (JTB)

Required for normal cytokinesis during mitosis. Plays a role in the regulation of cell proliferation.

Might be a component of the chromosomal passenger complex (CPC), a complex that acts as a key regulator of mitosis. The CPC complex has essential functions at the centromere in ensuring proper chromosome alignment and segregation and is required for chromatin-induced microtubule stabilization and spindle assembly.
