Applications: Substrate for histone methyltransferase or acetyltransferase assays. Ideal for screening small molecular inhibitors of histone methyltransferases and acetyltransferases for drug discovery and HTS applications. Since the recombinant histone proteins in thi
Background: The histone octamer is composed of a central heterotetramer of two copies of both histones H3 and H4, flanked by two heterodimers of histones H2A and H2B. The octamer assembles when the H3/H4 tetramer complexes with two H2A/H2B dimers. These histones of the histone octamer all contain N-terminal tails that emanate from their central histone folds and are targets for epigenetic modification.
Description: Human recombinant histone octamer consisting of 2 molecules each of histones H2A (a.a. 1-130(end)), H2B (a.a. 1-126(end)), H3 (a.a. 1-136(end)), and H4 (a.a. 1-103(end)), expressed in an E. coli expression system.
