Histone modifications and exercise adaptations
... II HDACs 4 and 5 occurs after their phosphorylation by upstream kinases. There are well described links between HDAC4 and CaMKII (2, 6, 9) and exercise increases both CaMKII activity and phosphorylation (23, 32). Furthermore, activation of CaMKII appears to be critical for histone hyperacetylation a ...

Differential roles of TGIF family genes in mammalian reproduction Open Access

TGIF2 arose from TGIF1 by duplication, whereas TGIFLX arose by retrotransposition to the X-chromosome. These genes have not been characterised in any non-eutherian mammals. We therefor ...
