WebJul 12, 2024 · The CFIm25 subunit of the heterotetrameric cleavage factor Im (CFIm) is a critical factor in the formation of the poly(A) tail at mRNA 3′ end, regulating the recruitment of polyadenylation factors, poly(A) site selection, and cleavage/polyadenylation reactions. We previously reported the homologous protein (EhCFIm25) in Entamoeba histolytica, … WebMay 21, 2024 · Cleavage factor I mammalian (CFIm) complex, composed of cleavage and polyadenylation specificity factor 5 (CPSF5) and serine/arginine-like protein CPSF6, regulates alternative polyadenylation (APA). Loss of CFIm function results in proximal polyadenylation site usage, shortening mRNA 3' untranslated …
