FunctionFodrin, 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.
Involvement in diseaseDefects in SPTAN1 are the cause of epileptic encephalopathy early infantile type 5 (EIEE5) [MIM:613477]. EIEE5 is a disorder characterized by seizures associated with hypsarrhythmia profound mental retardation with lack of visual attention and speech development, as well as spastic quadriplegia.
Sequence similaritiesBelongs to the spectrin family. Contains 3 EF-hand domains. Contains 1 SH3 domain. Contains 23 spectrin repeats.
Post-translational modificationsPhosphorylation of Tyr-1176 decreases sensitivity to cleavage by calpain in vitro.
Cellular localizationCytoplasm > 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.
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Alpha Fodrin antibody [D8B7] (ab11755)This image is courtesy of an anonymous Abreview
ab11755 at 1/100 staining mouse gut (small bowel) tissue sections by IHC-P. The tissue was paraformaldehyde fixed and a heat mediated antigen retrieval step in citrate buffer was performed before the tissue was blocked and incubated with the antibody for 45 minutes. An HRP conjugated goat anti-mouse antibody was used as the secondary.
