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.
Protein type: Protease; EC 126.96.36.199; Ubiquitin-specific protease; EC 3.4.19.-
SS: The number of records in which this modification site was determined using site-specific methods. SS methods include amino acid sequencing, site-directed mutagenesis, modification site-specific antibodies, specific MS strategies, etc.
