The nucleosome, made up of four core histone proteins (H2A, H2B, H3 and H4), is the primary building block of chromatin. In addition to the growing number of post-translational histone modifications regulating chromatin structure, cells can also exchange canonical histones with variant histones that can directly or indirectly modulate chromatin structure (1). There are five major variants of histone H2A: canonical H2A (most abundant), H2A.X, MacroH2A, H2ABbd and H2A.Z (2). Histone H2A.Z, the most conserved variant across species, functions as both a positive and negative regulator of transcription and is important for chromosome stability (2). Several homologous protein complexes, such as SWR-C ( ), TIP60 ( ) and SRCAP (mammals), have been shown to catalyze the ATP-dependent exchange of H2A.Z for H2A in the nucleosome (3,4,5). This exchange of histone H2A variants changes histone-histone interactions in the nucleosome core and alters an acidic patch on the surface of the nucleosome, resulting in changes in nucleosome stability and binding of non-histone proteins such as HP1α (6,7).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nH2A histone family member Z; H2A histone family, member Z; H2A.z; H2A.Z variant histone 1; H2A.Z-1; H2A\/z; H2AFZ; H2AZ; H2AZ histone; H2AZ1; Histone H2A.Z; MGC117173\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R Mk Z\nSENSITIVITY: Endogenous\nMW (kDa): 14\nSOURCE: Rabbit","brand":"CST","offers":[{"title":"Default Title","offer_id":46797943668905,"sku":"2718S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-2718s","provider":"Iright","version":"1.0","type":"link"}
