Tyrosine Phosphatase | Target | Effect on Inflammasome Activation | Reference |
---|---|---|---|
PTPN22 | NLRP3 Tyr861 | De-phosphorylates NLRP3 to allow efficient inflammasome activation | [55,64] |
PTPN2 | JNK, Syk | Inhibits JNK/Syk mediated ASC phosphorylation and subsequent ASC speck formation | [114] |
PTPN11 (SHP2) | ANT-1 in mitochondrial wall | Inhibits excessive NLRP3 activation via enhancing mitochondrial stability/preventing mitochondrial cell wall damage | [124,128] |
PTP-S2 | p53 | Dephosphorylates p53 and thereby reduces its stability to prevent (excessive) p53-mediated CASPASE1 gene transcription/caspase-1 protein accumulation and activation | [134,135] |
