{{Short description|Protein-coding gene in the species Homo sapiens}}
{{Infobox_gene}}
'''Tristetraprolin''' (TTP), also known as '''zinc finger protein 36 homolog''' (ZFP36), is a [protein](/source/protein) that in humans, mice and rats is encoded by the ''ZFP36'' [gene](/source/gene).<ref name="pmid1699942">{{cite journal |vauthors=DuBois RN, McLane MW, Ryder K, Lau LF, Nathans D | title = A growth factor-inducible nuclear protein with a novel cysteine/histidine repetitive sequence | journal = J Biol Chem | volume = 265 | issue = 31 | pages = 19185–91 |date=Dec 1990 | doi = 10.1016/S0021-9258(17)30642-7 | pmid = 1699942 | doi-access = free }}</ref><ref name="entrez">{{cite web | title = Entrez Gene: ZFP36 zinc finger protein 36, C3H type, homolog (mouse)| url = https://www.ncbi.nlm.nih.gov/gene?Db=gene&Cmd=ShowDetailView&TermToSearch=7538}}</ref> It is a member of the TIS11 ([TPA](/source/12-O-Tetradecanoylphorbol-13-acetate)-induced sequence) family, along with [butyrate response factors 1](/source/ZFP36L1) and 2.<ref name="pmid21278925">{{cite journal |vauthors=Sanduja S, Blanco FF, Dixon DA | title = The roles of TTP and BRF proteins in regulated mRNA decay | journal = Wiley Interdiscip Rev RNA | volume = 2 | issue = 1 | pages = 42–57 | year = 2011 | pmid = 21278925 | pmc = 3030256 | doi = 10.1002/wrna.28 }}</ref>

TTP binds to [AU-rich element](/source/AU-rich_element)s (AREs) in the 3'-untranslated regions (UTRs) of the [mRNAs](/source/messenger_RNA) of some [cytokine](/source/cytokine)s and promotes their degradation. For example, TTP is a component of a [negative feedback](/source/negative_feedback) loop that interferes with [TNF-alpha](/source/Tumor_necrosis_factor-alpha) production by destabilizing its mRNA.<ref name="pmid9703499">{{cite journal |vauthors=Carballo E, Lai WS, Blackshear PJ | title = Feedback inhibition of macrophage tumor necrosis factor-alpha production by tristetraprolin | journal = Science | volume = 281 | issue = 5379 | pages = 1001–5 |date=August 1998 | pmid = 9703499 | doi = 10.1126/science.281.5379.1001| bibcode = 1998Sci...281.1001C | url =  https://zenodo.org/record/1231137}}</ref>  Mice deficient in TTP develop a complex syndrome of inflammatory diseases.<ref name="pmid9703499"/>

==Interactions==
ZFP36 has been shown to [interact](/source/Protein-protein_interaction) with [14-3-3 protein](/source/14-3-3_protein) family members, such as [YWHAH](/source/YWHAH),<ref name="pmid11886850">{{cite journal |vauthors=Johnson BA, Stehn JR, Yaffe MB, Blackwell TK | title = Cytoplasmic localization of tristetraprolin involves 14-3-3-dependent and -independent mechanisms | journal = J.

==Regulation==
[Post-transcriptionally](/source/Post-transcriptional_regulation), TTP is regulated in several ways.<ref name="pmid21278925"/> The [subcellular localization](/source/subcellular_localization) of TTP is influenced by interactions with protein partners such as the 14-3-3 family of proteins. These interactions and, possibly, interactions with target mRNAs are affected by the phosphorylation state of TTP, as the protein can be posttranslationally modified by a large number of [protein kinase](/source/protein_kinase)s.<ref name="pmid21278925"/> There is some evidence that the TTP transcript may also be targeted by [microRNA](/source/microRNA)s, such as [miR-29a](/source/mir-29_microRNA_precursor).<ref name="pmid21278925"/>
