Gene Snapshot
Salivary gland secretion 7 (Sgs7) encodes one of the 20-hydroxyecdysone-induced proteins secreted at the larval-to-prepupal transition. They form a glue that serves to attach the prepupa and pupa to a solid substrate. [Date last reviewed: 2019-03-14]

    Phenotypic Description (Red Book; Lindsley and Zimm 1992)
    Sgs7
    Encodes the 5481 kd salivary-gland glue protein, SGS7; the protein contains, in common with SGS3 and SGS8, a 23-residue amino-terminal signal peptide and a carboxy-terminal region of about 50 amino acids that shows considerable homology with that of SGS3 and SGS8; it is not glycosylated. Expressed coordinately with Sgs3 and Sgs8.

              Gene expression is unaffected in Eip74EFneo24 mutants but transcripts are barely detectable in Eip74EFDL-1 mutants.

              Ecdysteroid-regulated gene.

              Sgs7 encodes the 5481kD salivary-gland glue protein. One of a group of seven genes encoding proteins that are components of the secretion produced by the larval salivary glands during the third instar for the purpose of attaching the larva to the substrate preparative to pupariation. The protein contains, in common with those encoded by Sgs3 and Sgs8, a 23-residue amino-terminal signal peptide and a carboxy-terminal region of about 50 amino acids that shows considerable homology with those encoded by Sgs3 and Sgs8; it is not glycosylated. Expressed coordinately with Sgs3 and Sgs8.

              A cis-acting element required for the correct expression of both Sgs7 and Sgs8 is located asymmetrically in the intergenic region between the two genes.

              Cessation of Sgs7 transcription and puff regression are ecdysterone-dependent.

              Initiation of transcription of Sgs7, but not of intermolt-puff formation seems to depend on the presence of suitable levels of ecdysterone in early third instar larvae.

              Identification: During a molecular analysis of the 68C puff locus.

              Sgs7 and Sgs8 are oppositely oriented so that their promoters are adjacent, suggesting that this pair may form a single regulated unit. The pair is bounded by an inverted repeat of 0.3kb elements.

              Sequences located 5' to Sgs7, Sgs8, Sgs3, the Hsp70 genes at 87A and 87C and the copia coding region are similar to the sequence at -405 from Sgs4.

              Synthesis of the glue proteins begins about 106 h after egg deposition and ceases abruptly within a few minutes after the glue is released 14 h later.

              Initiation of transcription of Sgs7 is coincident with the formation of the intermolt puffs in early to mid third instar.
