Source Description
UniProtComponent of the cleavage and polyadenylation specificity factor (CPSF) complex that play a key role in pre-mRNA 3'-end formation. May interact with poly(A) polymerase and other factors to bring about cleavage and poly(A) addition (By similarity). Mediates poly(A) site selection (PubMed:23136375). Binds RNA in a calcium-dependent manner (PubMed:16500995, PubMed:17576667, PubMed:20214900). Exhibits endonuclease activity with an ability to nick and degrade linear as well as circular single-stranded RNA that leaves RNA 3' ends with hydroxyl groups, thus mediating processing of the pre-mRNA as a prelude to the polyadenylation (PubMed:17576667). Involved in the post-transcriptional control, probably via poly(A) addition, of the responses of plants to stress, especially genes mediating tolerance to oxidative stress (PubMed:18545667). Plays a role in the regulation of salicylic acid (SA) production via the control of messenger RNA 3' end processing, thus being a key component of programmed cell death and plant immune responses required for resistance to virulent Pseudomonas syringae pv tomato DC3000 (Pst) (PubMed:24706550). {ECO:0000250|UniProtKB:O95639, ECO:0000269|PubMed:16500995, ECO:0000269|PubMed:17576667, ECO:0000269|PubMed:18545667, ECO:0000269|PubMed:20214900, ECO:0000269|PubMed:23136375, ECO:0000269|PubMed:24706550}.
