Co-immunoprecipitation of rat Stat5 and Prlrs mutated to have a single intracellular tyrosine suggests that phosphorylation of these tyrosines is required for Stat5 binding and leads to Stat5 tyrosine phosphorylation (Pezet et al. 1997). STAT1 and STAT3 have both been reported to be activated by PRLR (DaSilva et al. 1996), but the region(s) of PRLR required for activation of these Stats remains poorly documented.
