Rabbit BIM Polyclonal Antibody | anti-BIM antibody
BIM Antibody
Phosphate buffered saline, pH 7.4, 150mM NaCl, 0.02% sodium azide and 50% glycerol.
Function: Induces apoptosis and anoikis. Isoform BimL is more potent than isoform BimEL. Isoform Bim-alpha1, isoform Bim-alpha2 and isoform Bim-alpha3 induce apoptosis, although less potent than isoform BimEL, isoform BimL and isoform BimS. Isoform Bim-gamma induces apoptosis. Isoform Bim-alpha3 induces apoptosis possibly through a caspase-mediated pathway. Isoform BimAC and isoform BimABC lack the ability to induce apoptosis.
Subunit Structure: Forms heterodimers with a number of antiapoptotic Bcl-2 proteins, including MCL1, BCL2, BCL2L1 isoform Bcl-X(L), BCL2A1/BFL-1, BHRF1, and BCL2L2/BCLW (PubMed:11997495, PubMed:27013495, PubMed:18812174). Isoform BimS and isoform Bim-alpha3 interact with BAX; this interaction may lead to BAX activation through conformational change (PubMed:11997495). Does not heterodimerize with proapoptotic proteins such as BAD, BOK or BAK. Identified in a complex containing BCL2L11, DYNLL1 and BCL2L1 isoform Bcl-X(L); BH3 integrity is required for BCL2L1-binding. Interacts with YWHAZ. When phosphorylated, interacts with TRIM2; this interaction is associated with ubiquitination and degradation (PubMed:21478148). Interacts with MCL1; may sequester BCL2L11 to prevent its pro-apoptotic activity (PubMed:27013495, PubMed:17389404). When phosphorylated, isoform BimEL interacts with USP27X; this interaction leads to BCL2L11 deubiquitination and stabilization (PubMed:27013495).
Post-translational Modifications: Phosphorylation at Ser-69 by MAPK1/MAPK3 leads to interaction with TRIM2 and polyubiquitination, followed by proteasomal degradation (PubMed:15486195, PubMed:21478148). Deubiquitination catalyzed by USP27X stabilizes the protein (By similarity). Ubiquitination by TRIM2 following phosphorylation by MAPK1/MAPK3 leads to proteasomal degradation. Conversely, deubiquitination catalyzed by USP27X stabilizes the protein.
Similarity: The BH3 motif is required for interaction with Bcl-2 proteins and cytotoxicity. Belongs to the Bcl-2 family.

NCBI Description
The protein encoded by this gene belongs to the BCL-2 protein family. BCL-2 family members form hetero- or homodimers and act as anti- or pro-apoptotic regulators that are involved in a wide variety of cellular activities. The protein encoded by this gene contains a Bcl-2 homology domain 3 (BH3). It has been shown to interact with other members of the BCL-2 protein family and to act as an apoptotic activator. The expression of this gene can be induced by nerve growth factor (NGF), as well as by the forkhead transcription factor FKHR-L1, which suggests a role of this gene in neuronal and lymphocyte apoptosis. Transgenic studies of the mouse counterpart suggested that this gene functions as an essential initiator of apoptosis in thymocyte-negative selection. Several alternatively spliced transcript variants of this gene have been identified. [provided by RefSeq, Jun 2013]
