Gene Summary

α Spectrin (α-Spec) encodes an essential protein that interacts with the products of β-Spec or kst to form a heterotetramer. It is typically associated with the plasma membrane. It functions in a lipoprotein pathway that delivers dietary fat to the larval fat body for storage. It is also believed to function in asymmetric division of germ line stem cells via cytoplasmic structures called spectrosomes and fusomes. [Date last reviewed: 2019-03-21] (FlyBase Gene Snapshot)

Gene Snapshot

α Spectrin (α-Spec) encodes an essential protein that interacts with the products of β-Spec or kst to form a heterotetramer. It is typically associated with the plasma membrane. It functions in a lipoprotein pathway that delivers dietary fat to the larval fat body for storage. It is also believed to function in asymmetric division of germ line stem cells via cytoplasmic structures called spectrosomes and fusomes. [Date last reviewed: 2019-03-21]

Protein Function (UniProtKB)

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. Essential for larval survival and development. Stabilizes cell to cell interactions that are critical for the maintenance of cell shape and subcellular organization within embryonic tissues. Lva and spectrin may form a Golgi-based scaffold that mediates interaction of Golgi bodies with microtubules and facilitates Golgi-derived membrane secretion required for the formation of furrows during cellularization.

(UniProt, P13395)

Phenotypic Description (Red Book; Lindsley and Zimm 1992)

l(3)62Bd

Hemizygotes die in first larval instar, with one of seven alleles tested occasionally surviving until the second instar.

αSpec: alpha Spectrin

Structural gene for alpha spectrin, a 234 kd polypeptide that forms an elongated heterodimer with beta spectrin to form an important cytoskeletal component. Product crossreacts with antibodies against mammalian spectrins; can be shown to bind to beta spectrin subunits.

Summary (Interactive Fly)

cytoskeletal protein - structural and docking protein - acts together with integrins to regulate actomyosin and columnarization, and to maintain a mono-layered follicular epithelium

The regions of the tail ends of the α-Spec and

β-Spec@ chains that are necessary for interchain binding were mapped in

vitro. Segments 20 and 21 and part of 22 of the α chain and segments 2

and 3 and part of 1 of the β chain are required for interchain binding.

External Data

Subunit Structure (UniProtKB)

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. Interacts with calmodulin in a calcium-dependent manner, interacts with F-actin and also interacts with Lva. Interacts with Ten-m.

Subunit Structure (UniProtKB)

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. Interacts with calmodulin in a calcium-dependent manner, interacts with F-actin and also interacts with Lva. Interacts with Ten-m.

Additional comments

One or more of the processed transcripts for this gene share(s) untranslated sequences with a transcript of an adjacent gene, but encode(s) a single open reading frame (ORF). The non-overlapping ORFs that share untranslated sequences are represented by dlt and α-Spec.

(FlyBase Genome Annotators, 2002-2003)

Other Comments

α-Spec functions, with β-Spec, at the presynapse as an essential presynaptic scaffold that may link synaptic cell adhesion with the stabilization of the underlying microtubule cytoskeleton.

(Pielage et al., 2005)

dsRNA made from templates generated with primers directed against this gene tested in RNAi screen for effects on Kc167 and S2R⁺ cell morphology.

(Kiger et al., 2003)

The dlt open reading frame is located within the first intron of α-Spec and the two genes share a common first untranslated exon. Overall orientation not stated: Patj- CG12020- Cdc37- α-Spec+ dlt+ α-Spec+

(Pielage et al., 2003)

Spectrin is necessary for the capture and tethering of membrane associated proteins required for presynaptic neurotransmitter release.

(Featherstone et al., 2001)

The absence of spectrins disrupts neurotransmission but does not alter postsynaptic glutamate receptor field function or the ultrastructural localization of presynaptic vesicles. The subcellular location of many synaptic proteins is affected.

(Featherstone et al., 2001)

Four EMS induced alleles were identified in a screen for mutations affecting commissure formation in the CNS of the embryo.

(Hummel et al., 1999)

α-Spec is required for ovarian follicle monolayer integrity. Elimination of α-Spec from follicle cells does not appear to prevent the assembly of conventional β-Spec and Ank products at the lateral domain of the follicle cell plasma membrane. However α-Spec is required for the correct localization of Β_H-spectrin to the apical surface.

(Lee et al., 1997)

The α-Spec gene product is a component of both fusomes and spectrosomes.

(de Cuevas et al., 1996)

Clonal analysis demonstrates α-Spec is required in the germline (but not in the follicle cells) for cyst formation and oocyte differentiation. Its role in each process is distinct from that of hts protein. The organisation of membrane skeletal proteins is more dependent on α-Spec in the fusome than at the plasma membrane in other cells. The fusome and associated membrane skeleton play a central role in regulating the divisions and differentiation of cyst cells.

(de Cuevas et al., 1996)

The results of clonal analysis suggest that spectrin is involved in the spatial arrangement of the follicle cell population during oocyte development.

(Lee et al., 1995)

The hts and α-Spec products are components of the fusome, which is required for ovarian cyst formation.

(Lin et al., 1994)

Recombinant proteins constructs of α-Spec and β-Spec, whose primary structures correspond to the regions required for tail end interchain binding (segments 19-22 of α-Spec and segments 1-4 of β-Spec), demonstrate that interchain binding depends on multiple sites within both the nonrepetitive segments and adjacent repetitive segments of both chains.

(Viel and Branton, 1994)

The structure of one of the repetitive segments of α-Spec has been determined at 1.8 angstrom resolution. The segment consists of a three helix bundle. Hydrophobic interactions between two tandem segments may constrain intersegment flexibility.

(Yan et al., 1993)

Various regions of the α-Spec molecule exhibit structural autonomy thus enabling fragments of the molecule to fold properly when expressed in bacteria. Results localise the calmodulin binding and calcium binding sites within specific segments of the protein.

(Dubreuil et al., 1991)

Single repetitive motifs and pairs of motifs can fold into stable conformations similar to that of native α-Spec when their N-terminal ends are 26 residues downstream of the residue that has usually been designated to be the first position of each repetitive motif.

(Winograd et al., 1991)

Mutant hemizygotes are larval lethal; dying in the first or (rarely) second instar.
