... function of JIP proteins has been previously proposed for two other transcription factors, c-Myc and Max [11]. Inter- estingly, the region of JLP that binds Myc is similar to the region of JSAP1 binding ... in GST–hsMOK2 constructs. Incubation of these fusion proteins with recombinant Aurora A revealed a minor reduction in phosphorylation of the mutant containing only the S146A mutation (...
