| Biochem/physiol Actions【生化/生理作用】 | H4 (histone 4) is a core histone protein which is mobilized during herpes simplex virus 1 (HSV1) infection. This leads to elevated pools of free H2B and H4 and decreased rate of H2B fast chromatin exchange. Free H4 associates with HSV1 genomes, and this mobilization is also linked with the organization of H2A-H2B and H3-H4 dimers into unstable nucleosomes with HSV-1 genomes. The histone chaperone nuclear autoantigenic sperm protein (NASP) is responsible for maintaining a reservoir of soluble H3-H4 histones, where it regulates the activity of heat shock proteins Hsc70 and Hsp90, which target H3-H4 for degradation by chaperone-mediated autophagy. This reservoir level, in turn, depends upon the level of NASP. |
