표적 설명

Histone H3 (UniProt: P68431; also known as Histone H3/a, Histone H3/b, Histone H3/c, Histone H3/d, Histone H3/f, Histone H3/h, Histone H3/I, Histone H3/j, Histone H3/k, Histone H3/l) is encoded by the HIST1H3A (also known as H3FA, HIST1H3B, H3FL, HIST1H3C, H3FC, HIST1H3D, H3FB, HISTH3F, H3FD, HIST1H3F, H3FI, HIST1H3G, H3FH, HIST1H3H, H3FK, HIST1H3I, H3FF, HIST1H3J, H3FJ) gene (Gene ID: 8350, 8351, 8352, 8354, 8355, 8356, 8357, 8358, 8968) in human. Histones and DNA assemble to form nucleosomes and each nucleosome organizes a stretch of DNA wrapped around a histone octamer that is composed of a central (H3-H4)2 tetramer, flanked by two H2A-H2B dimers. A large number of variants of Histone H3 have been described in mammals. The two main variants, H3.1 and H3.3, show different genomic localization patterns in animals. They possess distinct histone chaperones, CAF-1 and HIRA, which play important role in mediating DNA-synthesis-dependent and -independent nucleosome assembly. Histone H3.1 serves as the canonical histone, which is incorporated during DNA replication, whereas H3.3 acts as the replacement histone that can be incorporated outside of S-phase during chromatin-disrupting processes like transcription. Histone H3 features a main globular domain and a long N-terminal tail, which protrudes from the globular nucleosome core and can undergo several different types of epigenetic modifications that influence cellular processes. The amino-terminal tails of histone proteins are subject to several posttranslational modifications, including acetylation, methylation, and phosphorylation, which recruit downstream regulatory factors, influence chromatin structure, and are critical determinants of transcription. These modifications on histones, known as histone acyl marks, are involved in transcription regulation. However, the exact role of other modifications, such as propionylation and butyrlation are still under investigation. These modifications are detected at comparable levels to acetylation on selected residues in histone H3. Butyrlation of lysine 9 in histone H3 that occurs in cecal epithelial cells is shown to shown to decrease upon antibiotic treatment. This diminution can be rescued by treatment with exogenous tributyrin. (Ref.: Scott, WA., and Campos, EI. (2020). Front. Cell Dev. Biol. 8; 701; Allis CD., and Jenuwein, T. (20160. Nat. Rev.
