WebJun 30, 2024 · There are three main histone H3 variants in metazoans: H3.1 and H3.2 that are known as the “canonical” histone H3, the replacement variant H3.3, and the centromere-specific variant CENP-A. Other variants include the testis-specific H3 variant H3t, and primate-specific variants H3.X and H3.Y. WebH3.3 is a subtype of H3 histone and can be encoded either by the H3F3A or H3F3B genes independently. Amino acids such as lysine and arginine found in the histone tails are sites of post-translational modifications (PTMs) such as methylation and acetylation. WebHaving recently reported that H3.3 G34W mutations are characteristic of this tumor type, we have now investigated the sensitivity and specificity of the anti-histone H3.3 G34W rabbit monoclonal antibody in a wide variety of tumors including histologic mimics of GCTB to assess its value as a diagnostic marker. grian limited life ep 4
