Anti-Histone H4, acetylated (Histone Cluster 4 H4, H4/p, HIST4H4, MGC24116)

Histone 4 is a 12-15kD member of the histone H4 family of molecules. It is ubiquitously expressed, with H4 initially synthesized and deposited in replicating chromatin during S phase. H4 undergoes multiple posttranslational modifications. At the G2/M transition, H4 is monomethylated on Lys20 and possibly contributes to transcription initiation/elongation. As the cell moves into the M/G1 phase, Lys20 becomes either dimethylated or trimethylated, contributing to DNA repair and telomere maintenance, respectively. H4 is also known to be phosphorylated on aa2-48, plus aa52-89, and acetylated on at least nine sites. Human histone 4 is 103aa in length. Full length histone 4 is identical in aa sequence to mouse histone 4, and 78aa identical to Tetrahymena histone 4 over aa2-20 used for immunization.
