Protein

Ribonuclease 3

Gene

drsh-1

Organism
Caenorhabditis elegans
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at transcript leveli

Functioni

Executes the initial step of microRNA (miRNA) processing in the nucleus, that is the cleavage of pri-miRNA to release pre-miRNA. Involved in pre-rRNA processing. Cleaves double-strand RNA and does not cleave single-strand RNA. Involved in fertility. Required for the function or synthesis of the let-7 miRNA.1 Publication

Catalytic activityi

Endonucleolytic cleavage to 5'-phosphomonoester.

Cofactori

Mg2+By similarity, Mn2+By similarity
