Supermembrane actions for Gaiotto-Maldacena backgrounds

We write down the supermembrane actions for M-theory backgrounds dual to general $\mathcal{N}=2$ four-dimensional superconformal field theories. The actions are given to all orders in fermions and are in a particular $\kappa$-gauge. When an extra U(1) isometry is present our actions reduce to $\kappa$-gauge fixed Green-Schwarz actions for the corresponding Type IIA backgrounds.
