WebLike most eukaryotic organisms, these parasites each contain at least two histone H3 variants, termed H3 and H3.3. Sequence analysis reveals the Apicomplexan H3 proteins harbor novel and rare features. Expression and purification of recombinant H3 variants will provide species-specific substrate for the analysis of the histone-modifying ... WebDec 31, 2014 · Using tandem mass spectrometry we localized four different clipping sites in H3 and one clipping site in H2B. We show that in spheroid culture clipped H3 proteoforms are mainly represented by canonical histone H3, whereas in primary hepatocytes over 90% of clipped H3 correspond to the histone variant H3.3.
WebPost-translational modifications (PTMs) of histone proteins play a fundamental role in regulation of DNA-templated processes.
