Target
Relevance
The conserved histone variant H2A.Z functions in euchromatin to antagonize the spread of heterochromatin. The mechanism by which histone H2A is replaced by H2A.Z in the nucleosome is unknown. However, the recently isolated SWR1 complex catalyzes an ATP-dependent histone exchange with specificity for the histone variant H2A.Z. This provides a new theme in chromatin remodeling mechanisms and an explanation of how histone variants are incorporated into the nucleosome outside of S phase. In connection with the isolation of histone variant specific chaperone complexes, we are beginning to see the mechanisms that mix the histone octamer with intriguing implications for epigenetic inheritance. During early mammalian development H2A.Z plays an essential, but unknown, function(s). It has been shown (Rangasamy et al., 2003) that undifferentiated mouse cells of the inner cell mass lack H2A.Z, but upon differentiation H2A.Z expression is switched on. Strikingly, H2A.Z is first targeted to pericentric hetero chromatin and then to other regions of the nucleus, but is excluded from the inactive X chromosome and the nucleolus.

Nucleosomes from 10-day chicken brain tissue were used in ChIP experiments. An acetic acid / urea / Triton gel was run and the corresponding western blot using ab18263 was used to compare proteins in the Bound chromatin fraction with those of the Input and Unbound fractions. In lane 10 there is a strong band corresponding to a hyper-acetylated H2A.Z.
