Rabbit Anti-phospho-Bim(Ser87)/FITC Conjugated antibody
background:
Bim, Bcl-2 interacting mediator of cell death, is a pro-apoptotic protein belonging to the Bcl2 family of proteins containing a Bcl2 homology domain 3 (SH3). It is proapoptotic and exerts its effects by interacting with prosurvival members of the Bcl2 family like Bcl2, BclxL and Bclw. Bim is sequestered in an inactive conformation through binding to the microtubule-associated dynein motor complex. Certain apoptotic stimuli release Bim from microtubules, allowing inhibitory binding to anti-apoptotic Bcl-2 family members and subsequent iniation of apoptosis.
Function:
Induces apoptosis. Isoform BimL is more potent than isoform BimEL. Isoform Bim-alpha1, isoform Bim-alpha2 and isoform Bim-alpha3 induce apoptosis, although less potent than the isoforms BimEL, BimL and BimS. Isoform Bim-gamma induces apoptosis.
Subunit:
Forms heterodimers with a number of antiapoptotic Bcl-2 proteins including MCL1, BCL2, BCL2L1 isoform Bcl-X(L), BCL2A1/SFL-1, and SHRF1. Does not heterodimerize with proapoptotic proteins such as BAD, BOK, BAX or BAK.
Subcellular Location:
Endomembrane system; Peripheral membrane protein. Note=Associated with intracytoplasmic membranes. Isoform BimEL: Mitochondrion. Isoform BimL: Mitochondrion. Isoform BimS: Mitochondrion. Isoform Bim-alpha1: Mitochondrion.
Tissue Specificity:
Isoform BimEL, isoform BimL and isoform BimS are the predominant isoforms and are ubiquitously expressed with a tissue-specific variation. Isoform Bim-gamma is most abundantly expressed in small intestine and colon, and in lower levels in spleen, prostate, testis, heart, liver and kidney.
Similarity:
Belongs to the Bcl-2 family.
