GRSF1 contains three RNA-binding domains, which are all required for high affinity RNA binding (Sofi et al. 2018). GRSF1 binds G-quadruplex secondary structures in RNA and promotes their melting, facilitating degradation of some RNAs by the SUPV3L1:PNPT1 complex (Pietras et al. 2018). However, GRSF1 acts to stabilize other RNAs and facilitates the translation of some mRNAs (Antonicka et al. 2013), therefore the melting of quadruplex G structures appears to have pleiotropic effects. GRSF1 also participates in processing large mitochondrial precursor transcripts to produce tRNAs, rRNAs, and mRNAs (Jourdain et al. 2013).
