It has also been proved that taf7l, as a paralogue of taf7 (transcription initiation factor TFIID subunit 7), cooperates with trf2 to regulate spermiogenesis (Zhou et al., 2013), and the variation of taf7 affects the genetic etiology of idiopathic male infertility (Pal et al., 2021). Here, TAF7L is linked to male infertility.
