Description: Cellular apoptosis susceptibility protein, the product of the CAS gene, is associated with microtubules and the mitotic spindle. CAS is the human homologue of the yeast chromosome-segregation gene, CSE-1. The molecular mechanism or function by which CAS is associated with cell proliferation and apoptosis is not yet fully understood. High expression of cytoplasmic CAS protein appears to correlate with proliferation of lymphoid cells. CAS expression may be useful in the identification of proliferating cells and in the elucidation of the function of cellular apoptosis.
