H4 Catalog Number H4100 Lyophilized Store At -20C Or -80C This product is an expressed human H4 protein composed of 102 amino acids. Histone H4 is one of the five main histone proteins involved in the structure of chromatin in eukaryotic cells. Featuring a main globular domain and a long N-terminal tail, H4 is involved with the structure of the nucleosome of the 'beads on a string' organization. Histone H4 is an important protein in the structure and function of chromatin,

CENPA-S68ph Catalog Number C16368 Lyophilized Store At -20C Or -80C Synthesized peptide corresponding to residues within 1-140 of CENP A with phosphorylation S68 modification. Histone modifications are associated with distinct transcription states and serve as heritable epigenetic markers for chromatin structure and function. Phosphorylation of Ser68 eliminates the binding of CENP-A to the assembly factor HJURP, thus preventing the premature loading of CENP-A to the

Types of histone modification Chromatin architecture, nucleosomal positioning, and ultimately access to DNA for gene transcription, is largely controlled by histone proteins. Each nucleosome is made of two identical subunits, each of which contains four histones: H2A, H2B, H3, and H4. Meanwhile, the H1 protein acts as the linker histone to stabilize internucleosomal DNA and does not form part of the nucleosome itself. Histone proteins undergo post-translational modification
