R1162-like plasmid antisense RNA is a 75-base RNA molecule which negatively regulates the RepI region of the plasmid.[1] The protein product of this gene region, along with another protein, controls the copy number of the 8.75kB R1162 plasmid.[2]
Experimental evidence has shown that in Escherichia coli, when levels of this RNA are decreased, the plasmid copy number of R1162 is increased.[1]
