The barrier-to-autointegration factor (BAF) is widely expressed in most human tissues and plays a critical role in chromatin organization, nuclear envelope assembly, gonadal development, and embryonic stem cell self-renewal. Complete loss ofBAF has been shown to lead to embryonic lethality and gonadal defects. TheBAF paralog, namely, barrier-to-autointegration factor 2 (BANF2), exhibits a testis-predominant expression pattern in both humans and mice. UnlikeBAF, it may cause isolated male infertility. Therefore, we used the CRISPR/Cas9 system to generateBanf2-knockout mice to further study its function in spermatogenesis. Unexpectedly, knockout mice did not show any detectable abnormalities in histological structure of the testis, epididymis, ovary, and other tissues, and exhibited normal fertility, indicating thatBanf2 is not essential for mouse spermatogenesis and fertility.Cytogenet Genome Res
