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.
Specificity
Natural and recombinant Rat Spectrin alpha chain, brain
Subcellular Location
Cytoplasm cytoskeleton Cytoplasm cell cortex Expressed along the cell membrane in podocytes and presumptive tubule cells during glomerulogenesis and is expressed along lateral cell margins in tubule cells.
Like erythrocyte spectrin, the spectrin-like proteins are capable of forming dimers which can further associate to tetramers. Interacts (via C-terminal spectrin repeats) with TRPC4 (By similarity). Interacts with CALM and EMD (By similarity). Interacts with isoform 1 of ACP1. Identified in a complex with ACTN4, CASK, IQGAP1, MAGI2, NPHS1 and SPTBN1.
