Small RNAs (21–24 nt) are involved in gene regulation through translation inhibition, mRNA cleavage, or directing chromatin modifications. At least five classes of these small regulatory RNAs (21–24 nt) have been characterized. miRNA and siRNA is reported frquently. However, the natural antisense miRNAs (nat-miRNAs) have not been reported in any system.
