CC -!- FUNCTION: Spectrin is the major constituent of the cytoskeletal network
CC underlying the erythrocyte plasma membrane. It associates with band 4.1
CC and actin to form the cytoskeletal superstructure of the erythrocyte
CC plasma membrane. Essential for larval survival and development.
CC Stabilizes cell to cell interactions that are critical for the
CC maintenance of cell shape and subcellular organization within embryonic
CC tissues. Lva and spectrin may form a Golgi-based scaffold that mediates
CC interaction of Golgi bodies with microtubules and facilitates Golgi-
CC derived membrane secretion required for the formation of furrows during
CC cellularization. {ECO:0000269|PubMed:11076973,
CC ECO:0000269|PubMed:3680372, ECO:0000269|PubMed:8276898}.
CC -!- SUBUNIT: Native spectrin molecule is a tetramer composed of two
CC antiparallel heterodimers joined head to head so that each end of the
CC native molecule includes the C-terminus of the alpha subunit and the N-
CC terminus of the beta subunit. Interacts with calmodulin in a calcium-
CC dependent manner, interacts with F-actin and also interacts with Lva.
CC Interacts with Ten-m. {ECO:0000269|PubMed:11076973,
CC ECO:0000269|PubMed:22426000}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton
CC {ECO:0000269|PubMed:11076973}. Golgi apparatus
CC {ECO:0000269|PubMed:11076973}. Cell projection, cilium, flagellum
CC {ECO:0000269|PubMed:20237161}. Note=Near the inner surface of the
CC plasma membrane of nearly all cells. Lva-alpha-spectrin complexes are
CC found at the Golgi. Localizes to the growing end of elongating
CC spermatid cysts (PubMed:20237161). {ECO:0000269|PubMed:20237161}.
CC -!- TISSUE SPECIFICITY: A substantial pool of maternal protein in the egg
CC undergoes dynamic changes in distribution early in embryogenesis. In
CC gastrulated embryo, the highest level of protein is found in the
CC respiratory tract cells and the lowest in parts of the forming gut.
CC {ECO:0000269|PubMed:2497103}.
CC -!- DEVELOPMENTAL STAGE: Expressed in elongating spermatid cysts during
CC spermatogenesis (at protein level) (PubMed:20237161). Expressed both
CC maternally and zygotically. {ECO:0000269|PubMed:20237161}.
CC -!- MISCELLANEOUS: Its transcript shares the first untranslated exon with
CC the dlt transcript, suggesting a common regulation.
CC -!- SIMILARITY: Belongs to the spectrin family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAL39886.1; Type=Erroneous initiation; Note=Truncated N-terminus.; Evidence={ECO:0000305};
CC Sequence=ABA81823.1; Type=Frameshift; Evidence={ECO:0000305};
