  • Function

    Fodrin, which seems to be involved in secretion, interacts with calmodulin in a calcium-dependent manner and is thus candidate for the calcium-dependent movement of the cytoskeleton at the membrane.
  • Tissue specificity

    Isoform 2 is present in brain, lung and kidney (at protein level).
  • Sequence similarities

    Belongs to the spectrin family.
    Contains 2 CH (calponin-homology) domains.
    Contains 1 PH domain.
    Contains 17 spectrin repeats.
  • Post-translational

    Isoform 2 is phosphorylated on Ser-8 and Ser-10.
  • Cellular localization

    Cell membrane and Cytoplasm > cytoskeleton. Cytoplasm > myofibril > sarcomere > M line. Colocalizes with ANK2 in a distinct intracellular compartment of neonatal cardiomyocytes.
