Protein

Nuclear and cytoplasmic polyadenylated RNA-binding protein PUB1

Gene

PUB1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

May be associated with hnRNA within the nucleus and remains associated during nucleocytoplasmic mRNA transport, once the proteins are in the cytoplasm, disassembly of PUB1-RNA complexes may occur prior to PAB1 binding and formation of a translationally competent RNP complex. Binds to polyadenylated RNA; prefers to bind poly(rU); binds to T-rich single-stranded DNA.
