         * [[miRNAs]]         * [[miRNAs]]
           * can also bind to the RNA molecule along with a ribonucleoprotein complex called the **RNA-induced silencing complex (RISC)** which rapidly degrades the target mRNA           * can also bind to the RNA molecule along with a ribonucleoprotein complex called the **RNA-induced silencing complex (RISC)** which rapidly degrades the target mRNA
 +        ***adenosine deaminases acting on RNA (ADARs) to produce different proteins**
 +          * a widespread post-transcriptional modification that converts adenosine to inosine (A to I) a mimic for guanosine during translation (especially in squid which have been shown to edit almost 8000 sites in 2,091 squid proteins)(([[https://www.cell.com/cell/fulltext/S0092-8674(26)01184-0|2026: Functional diversification of the cephalopod proteome by RNA editing]]))
 +          * ADARs can thus alter protein-coding sequences, splice sites, microRNA (miRNA) interactions, and innate immune sensing of endogenous RNA
 +          * in most animals, editing is limited and acts as a highly specialized regulatory buffer that fine-tunes RNA function on top of DNA-encoded sequences
 +          * only a small number of RNA editing events in mammals are known to exert physiological effects, such as the Q/R recoding of the AMPA receptor subunit GluA2, I/V recoding of Kv1.1, and R/R recoding of NEIL1
     * **translational**     * **translational**
       * mRNA binding to the ribosome       * mRNA binding to the ribosome
