Calcineurin — the Ca2+ regulated phosphatase and target of immunosuppressants — regulates GPCR-mediated phospholipid signaling at the plasma membrane. Here the authors show that CNAβ1 (a poorly studied isoform of the calcineurin catalytic subunit) is targeted to the plasma membrane through palmitoylation to dephosphorylate and promote PI4KA complex activity.
