Product Specific InformationPA1-978 detects proteasome 20S Y from purified bovine and human 26S proteasome samples.PA1-978 has been successfully used in Western blot and ICC/IF procedures. By Western blot, this antibody detects an ~25 kDa protein representing proteasome 20S Y from purified human 26S proteasome.The PA1-978 immunizing peptides correspond to amino acid residues 41-58 from human proteasome 20S Y and amino acid residues 74-91 from frog. These sequences are completely conserved in mouse, rat, and zebrafish. PA1-978 immunizing peptide (Cat. # PEP-173) is available for use in neutralization and control procedures.Target InformationProteolytic degradation is critical to the maintenance of appropriate levels of short-lived and regulatory proteins as important and diverse as those involved in cellular metabolism, heat shock and stress response, antigen presentation, modulation of cell surface receptors and ion channels, cell cycle regulation, transcription, and signalling factors. The ubiquitin-proteasome pathway deconstructs most proteins in the eukaryotic cell cytosol and nucleus. Other proteins are degraded via the vacuolar pathway which includes endosomes, lysosomes, and the endoplasmic reticulum. The 26S proteasome is an ATP-dependent, multisubunit (~31), barrel-shaped molecular machine with an apparent molecular weight of ~2.5 MDa. It consists of a 20S proteolytic core complex which is crowned at one or both ends by 19S regulatory subunit complexes. The 19S regulatory subunits recognize ubiquitinated proteins and play an essential role in unfolding and translocating targets into the lumen of the 20S subunit. The PA28/11S REG Activator protein complex functions as a proteolytic activator. This complex, consisting of alpha, beta, and gamma subunits, enhances the activity of the 20S proteolytic core. An enzymatic cascade is responsible for the attachment of multiple ubiquitin molecules to lysine residues of proteins targeted for degradation.

PSMB6 Antibody (PA1-978) in IFImmunofluorescent analysis of Proteasome 20S Y (green) showing staining in the cytoplasm and nucleus of A431 cells (right) compared to a negative control without primary antibody (left). Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with a Proteasome 20S Y polyclonal antibody (Product # PA1-978) in 3% BSA-PBS at a dilution of 1:20 and incubated overnight at 4 °C in a humidified chamber. Cells were washed with PBST and incubated with a DyLight-conjugated secondary antibody in PBS at room temperature in the dark. F-actin (red) was stained with a fluorescent red phalloidin and nuclei (blue) were stained with Hoechst or DAPI. Images were taken at a magnification of 60x. PSMB6 Antibody (PA1-978) in IFImmunofluorescent analysis of Proteasome 20S Y (green) in 3T3 cells. The cells were fixed with 4% paraformaldehyde for 15 minutes, permeabilized with 0.1% Triton X-100 in PBS for 15 minutes and blocked with 3% Blocker BSA (Product # 37525) in PBS for 30 minutes at room temperature. Cells were stained with or without Proteasome 20S Y rabbit polyclonal antibody (Product # PA1-978), at a concentration of 5 µg/mL for 1 hour at room temperature, and then incubated with a Goat anti-Rabbit (H+L) Superclonal Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034) at a dilution of 1:1000 for 1 hour at room temperature (both panels, green). Nuclei (both panels, blue) were stained with Hoechst 33342 dye (Product # 62249). Images were taken on a Thermo Scientific ToxInsight at 20X magnification.
