MCL-1

Myeloid cell leukemia sequence 1 (MCL-1) is an anti-apoptotic member of the BCL-2 family. Apoptosis is regulated by complex interactions between pro- and anti-apoptotic proteins in the BCL-2 family. MCL-1 inhibits apoptosis by directly binding the pro-apoptotic effector proteins BAK and BAX, and pro-apoptotic BH3-only proteins, such as BIM. The balance of the interaction between pro- and anti-apoptotic proteins in the BCL-2 family is essential for maintaining cellular homeostasis and determines whether a cell will undergo apoptosis in response to stress such as DNA damage.¹

Overexpression of MCL-1 has been widely reported in hematological malignancies and solid tumors and is associated with poor prognosis and resistance to treatment. Increased expression of MCL-1 can disrupt this balance and suppress cancer cell death.¹
