Superoxides 43-53 AKT serine/threonine kinase 1 Homo sapiens 7-10 20007513-11 2010 In conclusion, we found that depolarization of the MD during TGF leads to translocation of Rac to the apical membrane, which enhances O(2)(-) generation by the MD. Superoxides 134-137 AKT serine/threonine kinase 1 Homo sapiens 91-94
