MIB1 (gene)

MIB1 marker also used for detection of grades of astrocytoma E3 ubiquitin-protein ligase MIB1 is an is_associated_with::enzyme that in humans is encoded by the MIB1 is_associated_with::gene. It is involved in regulating is_associated_with::apoptosis.

Confusion with proliferative marker
An is_associated_with::antibody directed at the protein Ki-67, a product of the MKI67 gene, is called MIB-1. The MIB1 gene, which regulates apoptosis, should not be confused with the MIB-1 antibody, which is used to measure Ki-67 expression.
