Signal transducing adaptor molecule
Signal transducing adapter molecule 1 is a protein that in humans is encoded by the STAM gene.Function
This gene was identified by the rapid tyrosine-phosphorylation of its product in response to cytokine stimulation. The encoded protein contains an SH3 domain and the immunoreceptor tyrosine-based activation motif. This protein associates with JAK3 and JAK2 kinases via its ITAM region, and is phosphorylated by the JAK kinases upon cytokine stimulation, which suggests the function of this protein is as an adaptor molecule involved in the downstream signaling of cytokine receptors. HGS/HRS has been found to bind and counteract the function of this protein.Interactions
