RBM22 Activators

RBM22 Activators are a diverse collection of chemical compounds that influence cellular pathways leading to the enhanced activity of RBM22, a pivotal component in RNA splicing. Compounds like Forskolin and A23187 elevate intracellular cAMP and calcium levels, respectively, which are crucial for kinase signaling pathways that can enhance the RNA binding and splicing functions of RBM22. Similarly, PMA's activation of PKC and Ionomycin's modulation of calcium-dependent kinases may result in altered phosphorylation states that favor RBM22's splicing activity. The inhibition of protein phosphatases by compounds such as Okadaic acid and Calyculin A can also lead to a hyperphosphorylated splicing machinery, potentially boosting RBM22's role in spliceosome assembly and function. Moreover, Spermine directly stabilizes RNA structures, possibly improving RBM22's RNA binding efficiency, while EGCG's kinase inhibition might indirectly benefit RBM22's splicing activity by affecting overall phosphorylation patterns within the cell.

In addition to these activators, compounds like Paclitaxel and Jaspisamide influence cytoskeletal dynamics and nuclear architecture, which may indirectly enhance the assembly and function of the spliceosome where RBM22 operates. Anisomycin, by inhibiting protein synthesis, has the potential to trigger cellular responses that upregulate post-transcriptional modifications, playing into the hands of RBM22's splicing activities. Lastly, 5-Azacytidine can alter gene expression patterns, which may indirectly lead to a cellular environment favoring the splicing roles of RBM22.
