The gene Larval serum protein 1 α is referred to in FlyBase by the symbol Dmel\Lsp1α (CG2559, FBgn0002562). It is a protein_coding_gene from Drosophila melanogaster. It is reported to have molecular function: nutrient reservoir activity. The biological processes in which it is involved are not known. 7 alleles are reported. The phenotype of these alleles is annotated with: egg. It has one annotated transcript and one annotated polypeptide. Protein features are: Hemocyanin, C-terminal; Hemocyanin, N-terminal; Hemocyanin/hexamerin; Hemocyanin/hexamerin middle domain; Immunoglobulin E-set; Uncharacterised domain, di-copper centre. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of extremely high expression to a trough of no expression detected. Peak expression observed during late larval stages. Summary of FlyAtlas Anatomical Expression Data: Expression at high levels in the following post-embryonic organs or tissues: larval hindgut, larval fat body, larval salivary gland, larval trachea, larval carcass. Expression at moderate levels in the following post-embryonic organs or tissues: larval Malpighian tubules. Comments on Affy2 ProbeSet: ProbeSet 1631803_at completely aligns to an exonic region of the only FlyBase-annotated transcript isoform of Lsp1alpha. Gene sequence location is X:12384324..12387015.

Although X-linked Lsp1α is not dosage compensated (Roberts and Evans-Roberts, 1979b); however when relocated by transformation to an autosomal site or to an ectopic site on the X, the gene does show dosage compensation (Ghosh, Chatterje, Bunick, Manning and Lucchesi, 1989).
Lsp1 are three genes encoding three related polypeptides that combine in random hexamers to form LSP1, a heterogenous larval serum protein of 450,000 to 480,000 daltons (Wolfe, Akam and Roberts, 1977). LSP1 synthesized in fat body; appears early in third instar attaining peak levels at the white prepupal stage; level begins to decline at mid-pupal stage reaching base line about four days into adult life (Roberts, Wolfe and Akam, 1977). Highly homologous to one another and all three share amino-acid homology with LSP2. Antigenically related as well but antisera to LSP1 polypeptides do not crossreact with LSP2 (Brock and Roberts, 1980). Codes for the α polypeptide of LSP1; molecular weight 83,000 (Brock and Roberts, 1980).
