an adaptor protein involved in cytokine signal transduction the JAK-STAT cascade. Binds to the SH3 domain of the signal-transducing adaptor molecule STAM (signal transducing adaptor molecule). May play a critical role in cytokine-mediated signaling for MYC induction and cell cycle progression. Note: This description may include information from UniProtKB.
