Description

General description

Tristetraprolin (TTP, Nup 475, TIS11, G0S24, or ZFP36) is a member of the CCCH tandem zinc finger protein family. It is a nuclear RNA-binding protein that functions as a trans-acting factor. It is involved in post-transcriptional regulation of cytokine genes, most notably Tumor Necrosis Factor alpha (TNF-α). Upon activation by lipopolysaccharides, TTP binds TNF-α mRNA at AU-rich domains in the 3′-untranslated Region (3′-UTR) and induces deadenylation, thereby destabilizing the mRNA and tagging it for degradation. To produce this effect, TTP recruits other trans-acting factors to its C-terminal domain and mRNA-decay enzymes to its N-terminal domain. TTP is deactivated by phosphorylation driven by mitogen-activated protein kinase-activated protein kinase 2 (MK2) and p53. Therefore, TTP/MK2 regulates the biosynthesis of TNF-α and mediates inflammatory responses involving TNF-α. Knockout of TTP in mice produces arthritis, alopecia, dermatitis, among a range of other phenotypes related to overexpression of TNF-α.
