sh-dsRNA-1 is a synthetic double stranded RNA which contains one strand of RNA that translates to a copy of a piece of the human protein for kinesin family member 13A, transcript variant 1. It contains a maximum of 6005 base pairs. One strand will interfere with transcription/translation of the protein. Double-stranded RNA (dsRNA) is RNA with two complementary strands, similar to the DNA found in all cells. Double-strand RNA (dsRNA) may be a signal for gene-specific silencing of protein expression.
