A stress-dependent postembryonic role for the core CPA factor CFIM-1 in germline integrity.

ABSTRACT: Post-transcriptional processing of pre-mRNAs generates a diversity of 3' UTR transcript isoforms that can vary in their function and stability. The differential enrichment of transcript isoforms has been implicated in diseases ranging from cancer to neurodevelopmental disorders. However, the post-embryonic developmental roles of the core ensemble of cleavage and polyadenylation (CPA) factors that mediate these post-transcriptional changes remain poorly characterized. Here, we report a stress-dependent role for the core CPA factor CFIM-1 in germline integrity in Caenorhabditis elegans. Total loss-of-function of cfim-1 elicits a temperature-sensitive sterile phenotype in hermaphrodites. These changes in brood size are accompanied by broad sperm, oocyte and germline morphology d
