Dephosphorylation of JAKs by PTPs (R-HSA-877308) [Homo sapiens]


Protein tyrosine phosphatases (PTPs) SHP1 and SHP2 down regulate the IFNG signaling by dephosphorylating the tyrosine residues critical to the activation of JAK kinases. PTP1B interacts directly with JAK2 but not JAK1 and dephosphorylate the tyrosine Y1007 on JAK2.
