The proteasome is a multicatalytic proteinase complex with a highly ordered ring-shaped 20S core structure. The core structure is composed of 4 rings of 28 non-identical subunits; 2 rings are composed of 7 alpha subunits and 2 rings are composed of 7 beta subunits. Proteasomes are distributed throughout eukaryotic cells at a high concentration and cleave peptides in an ATP\/ubiquitin-dependent process in a non-lysosomal pathway. An essential function of a modified proteasome, the immunoproteasome, is the processing of class I MHC peptides. This gene encodes a member of the proteasome B-type family, also known as the T1B family, that is a 20S core beta subunit. This gene is located in the class II region of the MHC (major histocompatibility complex). Expression of this gene is induced by gamma interferon and this gene product replaces catalytic subunit 1 (proteasome beta 6 subunit) in the immunoproteasome. Proteolytic processing is required to generate a mature subunit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCross reactivity:\u003c\/strong\u003e No cross-reactivity with other proteins.\u003c\/p\u003e \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eQuantitative and spatial profiling: expression patterns are increasingly studied across cell states using multiplex imaging and omics-informed validation.\u003c\/li\u003e \u003cli\u003eIsoforms and post-translational modifications: researchers often evaluate how isoform composition and PTMs can shift apparent molecular weight or localization.\u003c\/li\u003e \u003cli\u003eContext-aware interpretation: comparative studies commonly include perturbations (stimulation, inhibition, genetic models) to relate target changes to pathway behavior.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWestern blot (WB):\u003c\/strong\u003e compare relative target abundance and apparent size shifts (e.g., isoforms\/PTMs) across conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunohistochemistry (IHC):\u003c\/strong\u003e assess distribution across tissue compartments and compare staining patterns between groups.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunofluorescence \/ ICC:\u003c\/strong\u003e evaluate subcellular localization and co-localization with compartment markers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow cytometry:\u003c\/strong\u003e quantify target-positive populations and compare shifts after stimulation or differentiation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAcross these uses, researchers typically interpret changes in signal as relative differences between matched sample groups, considering sample preparation and biological context.\u003c\/p\u003e \u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eApparent molecular weight can vary due to isoforms, proteolysis, glycosylation, phosphorylation, and sample preparation differences.\u003c\/li\u003e \u003cli\u003eSpecies reactivity and epitope conservation can influence observed signal patterns, especially in cross-species studies.\u003c\/li\u003e \u003cli\u003eControl concepts: include appropriate negative controls (e.g., isotype controls where relevant) and, when feasible, genetic or orthogonal controls (KO\/KD, peptide competition, or independent assays) to support interpretation.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eFor antibody reagents, monoclonal antibodies are often chosen for epitope consistency across lots, while polyclonals may recognize multiple epitopes and can show different background characteristics depending on context.\u003c\/p\u003e \u003c!-- Sources (internal): -
