Protein Information
Synonyms NEAS, SPTA2
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.
Cellular Location Cytoplasm, cytoskeleton. Cytoplasm, cell cortex. Note=Expressed along the cell membrane in podocytes and presumptive tubule cells during glomerulogenesis and is expressed along lateral cell margins in tubule cells.

Alpha Fodrin is a member of the spectrin family of widely distributed filamentous proteins that form a supporting and organizing scaffold for cell membranes (1). Non-erythroid alpha spectrin, also called Alpha Fodrin, is a major cortical cytoskeletal protein that has been implicated in the establishment of specialized membrane- cytoskeletal domains in differentiating cells (2-3). Cleavage of Alpha Fodrin accompanies apoptosis, induced by activation via the CD3/T cell receptor complex, ligation of the Fas (CD95) molecule and other Fas-expressing cells, or treatment of cells with staurosporine, dexamethasone, or synthetic ceramide (4). The major products of the cleavage are amino-terminal (135 kDa) and carboxy-terminal (150 kDa and 120 kDa) fragments. Antibodies against Alpha Fodrin are observed in diseases characterized by chronic apoptosis, and are valuable in the evaluation fo Sicca- and Sj鰃ren's syndrome (5-6).
