Protein Name: Methylthioribulose-1-phosphate dehydratase

UniprotKB/SwissProt ID: MTNB_MOUSE (Q9WVQ5)

Gene Name: Apip

Synonyms: Mmrp19

Organism: Mus musculus (Mouse).

Function: Catalyzes the dehydration of methylthioribulose-1- phosphate (MTRu-1-P) into 2,3-diketo-5-methylthiopentyl-1- phosphate (DK-MTP-1-P). Functions in the methionine salvage pathway, which plays a key role in cancer, apoptosis, microbial proliferation and inflammation. May inhibit the CASP1-related inflammatory response (pyroptosis), the CASP9-dependent apoptotic pathway and the cytochrome c-dependent and APAF1-mediated cell death.

Other Modifications: View all modification sites in dbPTM

Protein Subcellular Localization: Cytoplasm (By similarity).
