UniProt functional annotation for Q00963

UniProt code: Q00963.

Organism: Drosophila melanogaster (Fruit fly).
Taxonomy: Eukaryota; Metazoa; Ecdysozoa; Arthropoda; Hexapoda; Insecta; Pterygota; Neoptera; Endopterygota; Diptera; Brachycera; Muscomorpha; Ephydroidea; Drosophilidae; Drosophila; Sophophora.
 
Function: Spectrin is the major constituent of the cytoskeletal network underlying the erythrocyte plasma membrane. It associates with band 4.1 and actin to form the cytoskeletal superstructure of the erythrocyte plasma membrane. Interacts with calmodulin in a calcium-dependent manner. {ECO:0000269|PubMed:3680372}.
 
Subunit: Native spectrin molecule is a tetramer composed of two antiparallel heterodimers joined head to head so that each end of the native molecule includes the C-terminus of the alpha subunit and the N- terminus of the beta subunit.
Subcellular location: Cytoplasm, cytoskeleton. Cytoplasm, cell cortex.
Similarity: Belongs to the spectrin family. {ECO:0000305}.
Sequence caution: Sequence=AAR82828.1; Type=Miscellaneous discrepancy; Note=Contaminating sequence. Potential poly-A sequence.; Evidence={ECO:0000305};
