  • Title: [Novel function of Calcineurin--multipotential factor as protein a phosphatase].
    Author: Kondo E, Matsui H, Matsuo Y, Shibasaki F.
    Journal: Nihon Rinsho; 1998 Nov; 56(11):2973-81. PubMed ID: 9847629.
    Abstract:
    Calcineurin, serine/threonine phosphatase2B, is well known as a target of immunophilin-immunosuppressant complex such as cyclophilin-cyclosporinA and FKBP -FK506. It has been disclosed that Calcineurin is involved in interleukin 2 gene activation pathway lead to T lymphocyte proliferation, however, its functions as a multipotential factor still remains unknown. Here we mention about a new aspect of Calcineurin-involved pathway through its direct interaction to Bcl-2, an apoptosis suppressor. This direct binding of Calcineurin to Bcl-2 results in blockage of KFAT4 nuclear import by the prevention of Calcineurin-targetted dephosphorylation of NFAT4. Moreover, the tight binding between Calcineurin and Bcl-2 facilitate Bcl-2 activation as a apoptosis inhibitor through dephosphorylation of phosphorylated form of Bcl-2 serving to apoptosis regulation.
