CARF regulates the alternative splicing and piwi/piRNA complexes during mouse spermatogenesis through PABPC1.

ABSTRACT: ADP-ribosylation factor collaborator (CARF), which is also known as CDKN2AIP, was first recognized as an ADP-ribosylation factor-interacting protein that participates in the activation of the ARF-p53-p21 (WAF1) signaling pathway under different conditions, such as oxidative and oncogenic stresses. The activation of this pathway often leads to cell growth arrest and apoptosis as well as senescence. Previous studies revealed that CARF, an RNA-binding protein, is critical for maintaining stem cell pluripotency and somatic differentiation. Nevertheless, its involvement in spermatogenesis has not been well examined. In this study, we show that male mice deficient in Carf expression present impaired spermatogenesis and fertility. IP-MS and RNA-seq analyses reveal that CARF/ Carf in
