Protein

5'-3' exoribonuclease 2

Gene

RAT1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Possesses 5'->3' exoribonuclease activity. Required for the processing of nuclear mRNA, rRNA and small nucleolar RNA (snoRNA) precursors. May promote termination of transcription by RNA polymerase II via the recruitment of 3'-end processing factors to the poly(A) site and by the degradation of nascent RNA downstream of the poly(A) site.16 Publications

Catalytic activityi

Exonucleolytic cleavage in the 5'- to 3'-direction to yield nucleoside 5'-phosphates.

Cofactori

Mg2+2 Publications, Mn2+2 Publications

Enzyme regulationi

Inhibited by nucleoside 3', 5'-bisphosphates.1 Publication

pH dependencei

Optimum pH is 8.0-8.8.1 Publication
