mRNA-binding translational repressor and P-body disassembly factor; binds to the 5'UTR of mRNAs and inhibits cap-dependent and independent translational initiation; involved in mRNA binding under glucose starvation stress; associates with snR10 and snR11; HMT1-dependent arginine monomethylation modulates translational repression, mRNA decay and stress granule localization during glucose starvation; contains an intrinsically disordered RGG motif; localizes to P bodies and stress granules
