SOCS proteins bind to janus kinase and to certain cytokine receptors and signaling molecules, thereby suppressing further signaling events. Studies have shown that SOCS proteins are key physiological regulators of inflammation. Recent studies have also demonstrated that SOCS1 and SOCS3 are important regulators of adaptive immunity.Both SOCS1 and SOCS3 can inhibit JAK tyrosine kinase activity directly through their kinase inhibitory regions (KIR).

Dephosphorylation of eIF2α is central to ISR signal termination to restore protein synthesis and normal cell functioning 15. It is mediated by protein phosphatase 1 (PP1) complex that recruits a PP1 catalytic subunit (PP1c) and one of the two regulatory subunits. In mammals, phosphatase activity is regulated by either PPP1R15A (also known as growth arrest and DNA damage‐inducible protein, GADD34), which is induced as part of the ISR. the GADD34–PP1 complex acts as an important negative feedback loop to restore protein synthesis once the ER stress has been resolved, and as such aids in cell survival

FLT3-ITD kinase may regulate c-MYC through STAT5-induced enhancement of PIM kinases (Choudhary et al., 2009), which can modulate c-MYC stability and activity via phosphorylation (van der Lugt et al., 1995s). This is supported by the observation that FLT3-ITD CD34+ cells showed higher PIM activity compared to cells expressing FLT3-WT, indicated by increased expression of the PIM targets including p-BAD (Ser112), p-4EBP1 (Thr37/46), and p-c-MYC (Ser62) (Figure 6C); and by the observation that siRNA-mediated inhibition of PIM1, but not PIM2, expression resulted in significantly decreased p-c-MYC (Ser62), c-MYC, and SIRT1 expression in MV4-11 cells

SHANK proteins are ‘master’ scaffolding proteins that tether and organize intermediate scaffolding proteins. They are located at excitatory synapses, where they are crucial for proper synaptic development and function. SAPAP proteins subsequently bind to the PDZ domain of members of the SHANK protein family. SHANK proteins then bind to the actin cytoskeleton and to Homer protein, which in turn interacts with mGluRs. Through these extended links, PSD95, SAPAP, SHANK and Homer proteins form a quaternary complex that brings together mGluR and NMDAR complexes in the PSD (FIG. 3).
