Examples of post-transcriptional regulation upon T-cell activation. (A) Global regulation of RNA splicing upon T-cell activation. Splicing regulators (in blue) control alternative splicing and/or expression of T-cell receptor (CD25, CD62L, CD45), kinases (MKK7), paracaspases (MALT1), and cytokines (IL21) among other proteins. (B) CELF2-MKK7-JNK axis of enhanced TCR-mediated activation. (C) T-cell differentiation in modulated by the extension of MALT1 paracaspase activation, cleavage of Roquin and Regnase-1 RBP, and release repression of their mRNA targets.
