JAK2
We have expanded this observation by examining the effects of       progestins in the cytoplasm (level 2) where progestins regulate several       intracellular effectors by increasing the levels and altering the subcellular       compartmentalization of Stat5, increasing the association of Stat5 with       phosphotyrosine-containing proteins and tyrosine phosphorylation of JAK2, Cbl,       and Shc, and potentiating EGF-stimulated p42/p44 MAPKs, p38 MAP kinase, and JNK       activities.
