MASSIVE REGULATORS. “Micro-RNAs (miRNAs) represent a class of small non-coding RNAs (typically 19–23 nucleotides) which act by annealing to partially complementary binding sites present on the 3′ untranslated regions (UTR) of messenger RNAs (mRNAs) leading to inhibition of protein translation or by inducing mRNA decay. In mammals, miRNA regulate tissue-specific protein expression and are involved in virtually all cellular processes. Up to one-third of mammalian mRNAs are susceptible to miRNA-mediated regulation.”
