Role of RNA-binding proteins (RBPs) in T- and B-cell development. Conditional mouse models have revealed the importance of the RBP ZFP36L1 and ZFP36L2 in cell quiescence upon VDJ recombination to test and positively select those cells that have successfully recombined the BCR and TCR. C-NOT3 is related to successful VDJ recombination. These three RBPs and ELAVL1 are implicated in later expansion of double negative (DN) 3–4 T cells. ELAVL1, ZFP36, Roquin, and Regnase-1 are implicated in activation and differentiation of single positive T cells. ZFP318 is involved in IgD expression in transitional T2 B cells. ZFP36L1 and LIN28b have been involved in marginal zone (MZ) B-cell differentiation. hnRNPC and ELAVL1 are implicated in follicular (FO) B-cell maintenance.
