Description

BAG6, also known as BCL2-associated athanogene 6 or HLA-B-associated transcript 3, serves as a critical molecular chaperone regulator involved in protein quality control pathways. This multifunctional protein plays essential roles in the targeting of tail-anchored proteins to the endoplasmic reticulum, regulation of apoptosis, and modulation of immune responses through its association with MHC class I molecules. Its involvement in protein homeostasis and cellular stress responses makes BAG6 a significant target for researchers investigating proteostasis, cancer biology, and immunology.

This recombinant monoclonal antibody, clone 5H6, offers the consistency and reproducibility that demanding experimental workflows require. Produced using recombinant technology with a sequence-defined rabbit IgG format, it eliminates the lot-to-lot variability that can compromise longitudinal studies or multi-site collaborations. The antibody was raised against a synthesized peptide derived from human BAG6 and demonstrates cross-species reactivity with both human and mouse samples.

Validation across multiple platforms confirms this antibody's versatility in your research toolkit. Western blot analysis successfully detects BAG6 in human cell lines including SW620, NTERA-2, and HeLa, as well as mouse NIH/3T3 cells, with optimal performance at 1:500–1:2000 dilutions. The observed band at approximately 160 kDa, higher than the predicted 119 kDa molecular weight, likely reflects post-translational modifications such as glycosylation or the protein's proline-rich composition affecting gel migration. Immunofluorescence staining in HepG2 cells and flow cytometry analysis in K562 cells further demonstrate reliable performance for cellular localization and quantitative expression studies.

This antibody supports investigations into protein quality control mechanisms, ER-associated degradation pathways, and immune regulation research.

Target Background

Function

ATP-independent molecular chaperone preventing the aggregation of misfolded and hydrophobic patches-containing proteins. Functions as part of a cytosolic protein quality control complex, the BAG6/BAT3 complex, which maintains these client proteins in a soluble state and participates in their proper delivery to the endoplasmic reticulum or alternatively can promote their sorting to the proteasome where they undergo degradation. The BAG6/BAT3 complex is involved in the post-translational delivery of tail-anchored/type II transmembrane proteins to the endoplasmic reticulum membrane. Recruited to ribosomes, it interacts with the transmembrane region of newly synthesized tail-anchored proteins and together with SGTA and ASNA1 mediates their delivery to the endoplasmic reticulum. Client proteins that cannot be properly delivered to the endoplasmic reticulum are ubiquitinated by RNF126, an E3 ubiquitin-protein ligase associated with BAG6 and are sorted to the proteasome. SGTA which prevents the recruitment of RNF126 to BAG6 may negatively regulate the ubiquitination and the proteasomal degradation of client proteins. Similarly, the BAG6/BAT3 complex also functions as a sorting platform for proteins of the secretory pathway that are mislocalized to the cytosol either delivering them to the proteasome for degradation or to the endoplasmic reticulum. The BAG6/BAT3 complex also plays a role in the endoplasmic reticulum-associated degradation (ERAD), a quality control mechanism that eliminates unwanted proteins of the endoplasmic reticulum through their retrotranslocation to the cytosol and their targeting to the proteasome. It maintains these retrotranslocated proteins in an unfolded yet soluble state condition in the cytosol to ensure their proper delivery to the proteasome. BAG6 is also required for selective ubiquitin-mediated degradation of defective nascent chain polypeptides by the proteasome. In this context, it may participate in the production of antigenic peptides and play a role in antigen presentation in immune response. BAG6 is also involved in endoplasmic reticulum stress-induced pre-emptive quality control, a mechanism that selectively attenuates the translocation of newly synthesized proteins into the endoplasmic reticulum and reroutes them to the cytosol for proteasomal degradation. BAG6 may ensure the proper degradation of these proteins and thereby protects the endoplasmic reticulum from protein overload upon stress. By inhibiting the polyubiquitination and subsequent proteasomal degradation of HSPA2 it may also play a role in the assembly of the synaptonemal complex during spermatogenesis. Also positively regulates apoptosis by interacting with and stabilizing the proapoptotic factor AIFM1. By controlling the steady-state expression of the IGF1R receptor, indirectly regulates the insulin-like growth factor receptor signaling pathway.; Involved in DNA damage-induced apoptosis: following DNA damage, accumulates in the nucleus and forms a complex with p300/EP300, enhancing p300/EP300-mediated p53/TP53 acetylation leading to increase p53/TP53 transcriptional activity. When nuclear, may also act as a component of some chromatin regulator complex that regulates histone 3 'Lys-4' dimethylation (H3K4me2).; Released extracellularly via exosomes, it is a ligand of the natural killer/NK cells receptor NCR3 and stimulates NK cells cytotoxicity. It may thereby trigger NK cells cytotoxicity against neighboring tumor cells and immature myeloid dendritic cells (DC).; Mediates ricin-induced apoptosis.
