H2B.W1 (previously called H2BFWT) is an H2B variant specific to primate testis with hitherto unclear functions, although its single-nucleotide polymorphisms (SNPs) are closely associated with male non-obstructive infertility. Here, we found that H2B.W1 is only expressed in the mid-late spermatogonia stages, and H2B.W1 nucleosomes are defined by a more flexible structure originating from weakened interactions between histones and DNA. Furthermore, one of its SNPs, H2B.W1-H100R, which is associated with infertility, further destabilizes the nucleosomes and increases the nucleosome unwrapping rate by interfering with the R100 and H4 K91/R92 interaction. Our results suggest that destabilizing H2B.W1 containing nucleosomes might change the chromatin structure of spermatogonia, and that H2B.W1-H100R enhances the nucleosome-destabilizing effects, leading to infertility.
