Regulatory and functional architecture of 'Nested-Sensitivity' microexon programs
Neural microexons are a paradigmatic example of a cell type-specific transcriptomic program. Microexons are tiny exons that we revealed to have striking neuronal specificity established by their master splicing regulator Srrm4, which activates them during neuronal differentiation. However, our unpublished data challenge this on/off regulatory and functional paradigm. We found that a related paralog, Srrm3, is lowly but significantly expressed also in endocrine pancreas and, together with Srrm4, configure a 3-step switch of Srrm3/4 activity in pancreas (low), brain (mid) and retina (high). These different levels of expression activate increasingly larger subsets of microexons in the three…
