Regulation of mRNA stability by CCCH-type zinc-finger proteins in immune cells

Abstract

Current studies using knockout mice have revealed that some Cys–Cys–Cys–His (CCCH)-type zinc-finger proteins, namely tristetraprolin (TTP), Roquin and Regnase-1, play important roles in the immune system. These proteins are closely associated with the fate of their target RNAs in normal immune responses. However, the functions of many RNA-binding proteins have not been characterized precisely. To understand the molecular mechanisms of RNA metabolism in the immune system, investigation of TTP/Roquin/Regnase-1 might provide new knowledge. In this review, we will discuss the current understanding of these proteins in immune regulation and homeostasis and discuss RNA metabolism in the immune system.
