RASSF1A

MIM.605082 3p21.3

Definition: RASSF1A tumor suppressor functions as a regulator of the ordered proteolytic steps that organize mitosis. By controlling the stability of microtubules and the activity of the anaphase-promoting complex (APC), RASSF1A might provide a crucial link between mechanisms of tumor suppression and mitotic cell division.

BUB1B and RASSF1A genes play specific roles in the mitotic checkpoint, and their defects may cause chromosome instability or aneuploidy in mouse fibroblasts and human cancer cell lines; however, few studies have reported a correlation between defects in these genes and chromosome changes in human tumor samples.
