Induced Myeloid Cell Leukemia 1 Protein (Mcl-1)

Target
Mcl-1
Molecular classification
BCL-2 family protein, Anti-apoptotic protein
01

Overview

Induced myeloid cell leukemia 1 protein (Mcl-1) is a member of the BCL-2 family of proteins that regulates apoptosis. It acts as an anti-apoptotic factor by sequestering pro-apoptotic proteins like Bak and Bax, preventing mitochondrial outer membrane permeabilization. Mcl-1 expression is tightly regulated at multiple levels, and its overexpression is common in cancers, contributing to tumor survival and drug resistance. Therapeutic strategies target Mcl-1 through direct inhibition of the BH3-binding groove, transcription inhibition, translation inhibition, or promoting its degradation.
