Chromobox protein homolog 3 is a protein that is encoded by the CBX3 gene in humans. At the nuclear envelope, the nuclear lamina and heterochromatin are adjacent to the inner nuclear membrane. The protein encoded by this gene binds DNA and is a component of heterochromatin. This protein also can bind lamin B receptor, an integral membrane protein found in the inner nuclear membrane. The dual binding functions of the encoded protein may explain the association of heterochromatin with the inner nuclear membrane. This protein binds histone H3 tails methylated at Lys-9 sites. This protein is also recruited to sites of ultraviolet-induced DNA damage and double-strand breaks. Two transcript variants encoding the same protein but differing in the 5' UTR, have been found for this gene. Functional note: Seems to be involved in transcriptional silencing in heterochromatin-like complexes. Recognizes and binds histone H3 tails methylated at 'Lys-9', leading to epigenetic repression. May contribute to the association of the heterochromatin with the inner nuclear membrane through its interaction with lamin B receptor (LBR). Involved in the formation of functional kinetochore through interaction with MIS12 complex proteins. Contributes to the conversion of local chromatin to a heterochromatin-like repressive state through H3 'Lys-9' trimethylation, mediates the recruitment of the methyltransferases SUV39H1 and\/or SUV39H2 by the PER complex to the E-box elements of the circadian target genes such as PER2 itself or PER1. Reported localization: Nucleus . Associates with euchromatin and is largely excluded from constitutive heterochromatin. May be associated with microtubules and mitotic poles during mitosis (Potential). Expression\/tissue context: Widely expressed. Expressed at the highest levels in pancreas, heart, brain, skeletal muscle and placenta. Expressed at lower levels in lung, liver and kidney.\u003c\/p\u003e \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eChromatin Binding Proteins: Researchers commonly examine how CBX3 (Alpha-galactosidase A) relates to this theme using model systems and orthogonal readouts.\u003c\/li\u003e\n\u003cli\u003eEpigenetics and Nuclear Signaling: Researchers commonly examine how CBX3 (Alpha-galactosidase A) relates to this theme using model systems and orthogonal readouts.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eCommon research applications\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eWestern blotting: compare relative CBX3 (Alpha-galactosidase A) levels across conditions; band patterns may reflect isoforms and processing.\u003c\/li\u003e\n\u003cli\u003eIHC\/IHC-F: assess spatial distribution of CBX3 (Alpha-galactosidase A) across tissue regions and cell types using matched controls.\u003c\/li\u003e\n\u003cli\u003eIF\/ICC: evaluate subcellular localization and co-localization patterns; signal can depend on fixation\/permeabilization and epitope accessibility.\u003c\/li\u003e\n\u003cli\u003eFlow cytometry: quantify target-positive populations and shifts in expression; gating strategy and background staining controls are essential.\u003c\/li\u003e\n\u003cli\u003eELISA-compatible use: when applicable, interpret signal as relative abundance across sample sets with consistent handling and dilution strategy.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eSpecificity notes:\u003c\/strong\u003e No cross reactivity with other proteins.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eCross-reactivity:\u003c\/strong\u003e No cross-reactivity with other proteins.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eIsoforms and PTMs:\u003c\/strong\u003e Apparent size and signal patterns can differ across splice isoforms, proteolytic processing, and post-translational modifications.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eControls:\u003c\/strong\u003e Include an isotype control (as relevant), no-primary control for imaging, and orthogonal validation such as KD\/KO samples when available.\u003c\/li\u003e \u003c\/ul\u003e \u003c!-- Sources (internal): - UniProt entry for Q13185: https:\/\/www.uniprot.org\/uniprotkb\/Q13185\/entry - PubMed search (CBX3): https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=CBX3 - NCBI Gene search (CBX3): https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=CBX3 - Antibody validation concepts (NIH): https:\/\/www.nih.gov\/research-training\/rigor-reproducibility --\u003e","brand":"Boster Bio","offers":[{"title":"100 ug\/vial \/ Unconjugated","offer_id":53066862461293,"sku":"A01142","price":370.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Biotin","offer_id":53067427905901,"sku":"A01142-Biotin","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Cy3","offer_id":53067427938669,"sku":"A01142-Cy3","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro488","offer_id":53067427971437,"sku":"A01142-Fluoro488","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro550","offer_id":53067428004205,"sku":"A01142-Fluoro550","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro594","offer_id":53067428036973,"sku":"A01142-Fluoro594","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ FITC","offer_id":53067428069741,"sku":"A01142-FITC","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ HRP","offer_id":53067428102509,"sku":"A01142-HRP","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ APC","offer_id":53067428135277,"sku":"A01142-APC","price":820.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ PE","offer_id":53067428168045,"sku":"A01142-PE","price":820.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro647","offer_id":53067428200813,"sku":"A01142-Fluoro647","price":670.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Carrier Free","offer_id":53067428233581,"sku":"A01142-carrier-free","price":370.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/a01142-hp1-gamma-primary-antibodies-wb-testing-1.jpg?v=1772608339","url":"https:\/\/www.ebiohippo.com\/products\/anti-hp1-gamma-cbx3-antibody-picoband-bha21001489","provider":"BioHippo","version":"1.0","type":"link"}
