This gene encodes an anti-apoptotic protein, which is a member of the Bcl-2 family. Alternative splicing results in multiple transcript variants. The longest gene product (isoform 1) enhances cell survival by inhibiting apoptosis while the alternatively spliced shorter gene products (isoform 2 and isoform 3) promote apoptosis and are death-inducing.,MCL1,BCL2L3,EAT,MCL1-ES,MCL1L,MCL1S,Mcl-1,TM,bcl2-L-3,mcl1/EAT,MCL1,Cancer,Invasion and Metastasis,Cell Biology & Developmental Biology,Apoptosis,Bcl 2 family,Mitochondrial Control of Apoptosis,Inhibition of Apoptosis,Endocrine & Metabolism,Immunology & Inflammation,IL-6 Receptor Signaling Pathway,MCL1
