Involved in 3'-UTR mediated RNA regulation (By similarity). Complexes with PBP1 to promote mRNA interactions with poly(A)-binding protein (By similarity). Interacts with PBP1. Abnormal sexual reproduction; decreases MFalpha1 expression and abolishes hyphal elongation (PubMed:31681631). Decreases virulence in a mouse intranasal inhalation model for pulmonary infection (PubMed:31681631). Normal vegetative cell population growth at high temperature (PubMed:31681631). Belongs to the XPG/RAD2 endonuclease family. Although it belongs to the XPG/RAD2 endonuclease family, only one of the seven Asp residues involved in Mg(2+) binding are conserved suggesting that it has no nuclease activity.
