Chemical activators of MBNL2 predominantly work by modulating intracellular levels of cyclic nucleotides like cyclic AMP (cAMP) and cyclic GMP (cGMP). These molecules are integral components of intracellular signaling pathways and have a variety of cellular effects, including the modulation of protein kinases and transcription factors. Forskolin, IBMX, 8-Br-cAMP, Rolipram, Dibutyryl-cAMP,and Rp-8-Br-cAMPs are all chemicals known for their ability to increase intracellular cAMP levels. Higher cAMP concentrations can activate Protein Kinase A (PKA), a kinase that phosphorylates diverse cellular proteins, including transcription factors like CREB. CREB, when activated, can regulate a multitude of genes, including those involved in the RNA splicing process, a key function of MBNL2. Therefore, the indirect activation of MBNL2 can be achieved through the modulation of these cAMP-based pathways.
Similarly, 8-CPT-cAMP and 8-PIP-cAMP are cAMP analogs that selectively activate exchange proteins directly activated by cAMP (EPAC). EPAC proteins activate Rap1, a small GTPase that can influence multiple cellular pathways, again indirectly influencing MBNL2 activity. Sp-8-Br-cAMPs also increase intracellular cAMP levels and can consequently activate PKA, leading to an indirect influence on MBNL2 activity. On the other hand, 8-Br-cGMP and Sildenafil work by increasing intracellular cGMP levels. Increased cGMP can activate Protein Kinase G (PKG), which, like PKA, can influence several cellular proteins, including transcription factors and enzymes related to the RNA splicing process, thus indirectly activating MBNL2. Lastly, Dipyridamole, a non-specific phosphodiesterase inhibitor, can increase both cAMP and cGMP levels, activating both PKA and PKG. These kinases, in turn, can influence the activity of MBNL2. Overall, while there is currently no known direct chemical activator of MBNL2, these chemicals can indirectly influence MBNL2 activity through their effects on intracellular cyclic nucleotide levels, protein kinase activity, and transcription factor regulation.
