Protein

Nuclear polyadenylated RNA-binding protein NAB2

Gene

NAB2

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

Functioni

This essential protein binds to polyadenylated RNA and single-stranded DNA. It may be involved not only in RNA processing but also in transcription regulation. Believed to associate directly with nascent RNA polymerase II transcripts and remain associated during subsequent nuclear RNA processing reactions.

Miscellaneous

Present with 9670 molecules/cell in log phase SD medium.1 Publication
