Regulation of p21 by RNA-binding proteins (RBPs). Several groups of RBPs are found to regulate p21 expression. Alternative names are included in parentheses. These RBPs contain one or more RNA-binding motifs, including RNA recognition domain (RRM), hnRNP K homology domain (KH), arginine/glycine-rich box (RGG), and double stranded RNA binding motif (dsRBD).
