S1A SERINE PROTEASES - CHYMOTRYPSIN-LIKE -
Chymotrypsin-like serine proteases cleave substrates following one of the hydrophobic amino acids at the P1 position. (Adapted from FBrf0239469). Chymotrypsin-like serine proteases of the S1A family are endopeptidases that cleave substrates following one of the hydrophobic amino acids at the P1 position. (Adapted from FBrf0239469).
Protein Function (UniProtKB)
Major function may be to aid in digestion.

Phenotypic Description (Red Book; Lindsley and Zimm 1992)
Ser1: Serine protease 1
Expressed abundantly in larval gut. Mutants dncM11 and dncM14 show lower levels of Ser1 RNA than normal flies; levels of cAMP, however, are elevated in the mutants. The Ser1-related genes Ser2 and Ser3 (with same location and cytology) are not expressed differentially in dnc mutants.

  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)
  • Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

    Additional comments

    Similarity to cytologically mapped serine protease genes not checked.

    Characterization of LAP genes "Lap-A" and "Lap-D" from the distribution and enzymatic activity of their proteins reveals a striking resemblance to the description of Jonah genes in 99C ("Jon99Co", "Jon99Ci", "Jon99Cii" and "Jon99Ciii") and 99F ("Jon99Fi" and "Jon99Fii") and the pattern of expression of their transcripts. At least one of the Jonah genes in 99C or 99F may correspond to "Lap-A" or "Lap-D".

    Other Comments

    Shows particularly robust cycling of transcription in adult heads, as assessed by expression analysis using high density oligonucleotide arrays with probe generated during three 12-point time course experiments over the course of 6 days.

    In a sample of 79 genes with multiple introns, 33 showed significant heterogeneity in G+C content among introns of the same gene and significant positive correspondence between the intron and the third codon position G+C content within genes. These results are consistent with selection adding against preferred codons at the start of genes.

    D.melanogaster is polymorphic for the number of "Jonah" genes in 99C. In the "β" arrangement, 4 copies are present; Jon99Co, Jon99Ci, Jon99Cii and Jon99Ciii, with Jon99Ci and Jon99Cii representing a tandem duplication of an approximately 1.8kb fragment. In the "α" arrangement, this 1.8kb fragment is only present in one copy ("Jon99Cαi").

    Expressed abundantly in larval gut. Mutants dncM11 and dncM14 show lower levels of Jon99Cii RNA than normal flies; levels of cAMP, however, are elevated in the mutants. The Ser99Da-related genes Ser99Db and Ser99Dc (with same location and cytology) are not expressed differentially in dnc mutants.

    Origin and Etymology
    Discoverer
    Etymology

    One of a number of genes isolated from a cDNA library made from third instar salivary glands, but subsequently found not to be expressed in the salivary glands but instead expressed specifically and abundantly in the midgut (which resulted in contamination of the original cDNA library). This surprising discovery prompted the name "Jonah" for this family of genes, after the Biblical prophet who unexpectedly turned up in the gut.
