Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

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.
Subunit structure	Like erythrocyte spectrin, the spectrin-like proteins are capable to form dimers which can further associate to tetramers. The short form cannot bind to the axonal protein fodaxin. Interacts with ANK2. Ref.7
Subcellular location	Cytoplasm › cytoskeleton By similarity. Cytoplasm › myofibril › sarcomere › M-band By similarity. Note: Colocalizes with ANK2 in a distinct intracellular compartment of neonatal cardiomyocytes By similarity. Isoform 2: Cell membrane; Peripheral membrane protein; Cytoplasmic side By similarity.
Tissue specificity	Isoform 2 is present in brain, lung and kidney (at protein level). Ref.2
Post-translational modification	Isoform 2 is phosphorylated on Ser-8 and Ser-10 By similarity.
Sequence similarities	Belongs to the spectrin family. Contains 2 CH (calponin-homology) domains. Contains 1 PH domain. Contains 17 spectrin repeats.
