DNA- and RNA-binding protein, involved in several nuclear processes such as pre-mRNA splicing, apoptosis and transcription regulation (Probable). Ensures the correct splicing of genes involved in immunity to promote longevity in response to infection by pathogenic bacteria such as S.aureus (PubMed:32538777). The third RNA recognition motif, called PUMP domain, is atypical and may rather mediate homodimerization and/or protein-protein interactions. RNAi-mediated knockdown increases survival following infection by pathogenic bacteria S.aureus (PubMed:32538777). RNAi-mediated knockdown impairs the splicing of genes such as prg-2 and tos-1 following infection by S.aureus (PubMed:32538777). RNAi-mediated knockdown induces the expression of nlp-34, lys-3, irg-2, irg-1, M01G12.9, fmo-2 and cyp-37B1 under non-infected conditions (PubMed:32538777). RNAi-mediated knockdown increases the phosphorylation of pmk-1 (PubMed:32538777). Belongs to the RRM half pint family.
