Double-strand-specific pac1 ribonuclease

Gene

pac1

Organism
Schizosaccharomyces pombe (strain 972 / ATCC 24843) (Fission yeast)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Digests double-stranded RNA. Converts long double-stranded RNAs into short oligonucleotides, leaving 5'-phosphates on their cleavage products. Probably inhibits mating and meiosis by degrading a specific mRNA required for sexual development.1 Publication

Catalytic activityi

Endonucleolytic cleavage to 5'-phosphomonoester.

Cofactori

Mg2+1 Publication

pH dependencei

Optimum pH is 8.5. No activity at pH below 6.5 or above 9.5.1 Publication
