Description

General description

NUMA1 or NUMA protein is an interesting and major component of the nuclear matrix of eukaryotic cells. NUMA1 is a highly abundant protein component that appears to serve a non-structural role but is needed for mitotic spindle poles and centrosome formation as well as a linker of microtubules. These functions are important for proper cytokinesis and the setup of the proper polarity axis during cell division. NUMA1 resides in the nuclear matrix during interphase. NUMA1 dissociates from condensing chromosomes during early prophase, and relocates to the spindle poles via a dynein/dynamin complex, and it remains there until the anaphase onset. Thus NUMA1 then can be found in the nucleus during cell rest and cytoplasmically and centrosome localized during cytokinesis. NUMA1 phosphorylation occurs by CDK1 and phosphorylation increases solubility and promotes association with dynein and subsequent translocation to the spindle poles.
