High impact information on Lsp1beta

  • Taken together these data indicate that the 1.65 X 10(3) and 2.25 X 10(3) base segments of DNA upstream from the LSP1 alpha and LSP1 beta genes contain cis-acting regulatory elements necessary for correct tissue and temporal specificity of LSP1 gene expression [1].
  • The same chromosomal localization and genomic organization, different from that of D. melanogaster, is found in both species for the Lsp1beta and Lsp1gamma genes [2].
  • To understand the structural and functional differences between these two storage hexamers, the nucleotide sequence of the coding region of the Lsp-1 beta gene was determined for comparison with LSP-2 and a number of other arthropod hexamerins [3].
  • Lsp-1 beta is also more closely related to calliphorin with respect to the protein domain structure, the presence of a single intron in its gene, and the absence of glycosylation sites [3].
  • The Drosophila Lsp-1 beta gene. A structural and phylogenetic analysis [3].
 

Biological context of Lsp1beta

 

Anatomical context of Lsp1beta

  • To test its role in male courtship, fat body was feminized using the highly specific Larval serum protein promoter [4].
