Recombinant Human Phorbol-12-myristate-13-acetate-induced protein 1 (PMAIP1)

Uniprot Id

Q13794

Target Species

Human

Target Name

PMAIP1

Target Full Name

Phorbol-12-myristate-13-acetate-induced protein 1

Target Function

Promotes activation of caspases and apoptosis. Promotes mitochondrial membrane changes and efflux of apoptogenic proteins from the mitochondria. Contributes to p53/TP53-dependent apoptosis after radiation exposure. Promotes proteasomal degradation of MCL1. Competes with BAK1 for binding to MCL1 and can displace BAK1 from its binding site on MCL1. Competes with BIM/BCL2L11 for binding to MCL1 and can displace BIM/BCL2L11 from its binding site on MCL1.

Target Subcellular Location

Mitochondrion.

Target Protein Families

PMAIP1 family

Target Tissue Specificity

Highly expressed in adult T-cell leukemia cell line.

Target Background

This gene belongs to a pro-apoptotic subfamily within the BCL-2 protein family, referred to as the BCL-2 homology domain 3 (BH3)-only subfamily, which determine whether a cell commits to apoptosis. In response to death-inducing stimuli, BH3-only members inhibit the anti-apoptotic BCL-2 family members, which under steady-state conditions keep the multi-BH domain proteins BAX and BAK, in an inactive state.
