Cyclic AMP 73-77 mitogen-activated protein kinase 1 Homo sapiens 18-22 29551366-4 2018 The absence of Erk2 resulted in a complete loss of folate and cAMP chemotaxis suggesting that this MAPK plays an integral role in the signaling mechanisms involved with this cellular response. Cyclic AMP 62-66 mitogen-activated protein kinase 1 Homo sapiens 15-19
