SOCS-1 and SOCS-3 binds to p-JAK2 (R-HSA-877269) [Homo sapiens]

Reaction
Summation

SOCS-1 and SOCS-3 coprecipitates with JAK kinases upon IFNG stimulation and are able to inhibit the JAK-STAT pathway, although with different affinity and kinetics. SOCS1 and SOCS3 binds to phosphorylated JAK1/2 and prevent the tyrosine kinase activity of JAKs through their kinase inhibitory region (KIR), thereby inhibiting downstream IFNG signaling. SOCS1 may also prevent IFNG signaling by targeting the signaling machinery to ubiquitin-proteasomal degradation pathway.
