Protein

Tyrosine-protein kinase sid-3

Gene

sid-3

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

Functioni

Tyrosine-protein kinase which plays a role in RNA-mediated gene silencing by mediating import of double-stranded RNA (dsRNA) into cells. Not required for import of ingested dsRNA into intestinal cells but involved in subsequent export from intestinal cells to internal tissues.1 Publication

Catalytic activityi

ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate.PROSITE-ProRule annotation
