Chromatin immunoprecipitation (ChIP) is the main tool for assessing chromatin structure and regulation. The basis of chromatin immunoprecipitation is the enrichment of DNA fragments to which specific proteins or a certain class of histone are bound [77]. Then the DNA fragments that are enri...
N234 is important for H2B.8 function by expressing a mutated H2B.8 with the 234th asparagine replaced by lysine (H2B.8-N234K). The expression of H2B.8-N234K fully complemented theh2b.8sperm nuclear size phenotype (Fig.2a), which shows that N234 is not essential for H2B.8 function....
Originally identified over 40 years ago, histone acetylation has now become a model for understanding the role of histone modifications in modulating chromatin structure [4]. To this end, the his- tone acetyltransferase Gcn5 and its associated complexes have been shown to regulate the transcription ...

We propose that NUP153 is a key regulator of chromatin structure by mediating binding of CTCF and cohesin at cis-regulatory elements and TAD boundaries in mammalian cells. Through this function, NUP153 links NPCs to chromatin architecture allowing developmental genes and IEGs that are poised to ...
