Histone H2A Type 1 (human, recombinant)

Histone H2A type 1 (H2A.1) is a variant of the histone H2A protein that is encoded by H2AC11, previously known as HIST1H2AG, in humans. Histone H2A is a core histone that forms a dimer with histone H2B. Two histone H2A/H2B dimers form an octameric nucleosome with a histone H3/H4 tetramer, around which DNA wraps, allowing it to be condensed. Histone H2A can be post-translationally modified via methylation of the arginine at position 3 by protein arginine methyltransferase 1 (PRMT1), PRMT5, or PRMT6, which is associated with both transcriptional activation and repression. When methylated by PRMT7, it is associated with DNA damage repair. The arginine residue at position 3 of histone H2A is also subject to citrullination by protein arginine deiminase 4 (PAD4). H2A.1 levels are higher in peripheral blood mononuclear cells (PBMCs) isolated from patients with active systemic lupus erythematosus (SLE) compared to those with stable SLE, rheumatoid arthritis (RA), or non-SLE non-RA controls. Cayman's Histone H2A Type 1 (human, recombinant) protein can be used for Western blot and ELISA applications.Synonyms: H2A Clustered Histone 11, H2A Histone Family, Member P, H2A.1, H2AC11, H2AFP, HIST1H2AG, Histone H2A/ptl.
