C19 NON-PEPTIDASE HOMOLOGS -
C19 non-peptidase homologs are similar in amino acid sequence to USP deubiquitinases (C19 cysteine peptidases) but lack one or more of the expected catalytic residues. (Adapted from FBrf0239469.)
Phenotypic Description (Red Book; Lindsley and Zimm 1992)
ec: echinus
Eyes large and bulging. Eye surface rough; facets large. Wings rather short and broad. Body thickset. Tends to remove dorsocentrals (posterior more than anterior) and posterior notopleurals; may also add dorsocentrals anterior to anterior dorsocentrals whether or not posterior bristles removed (Sturtevant). Reduces number of mesopleural hairs in h homozygotes (Sturtevant, 1969, Dev. Biol. 21: 48-61). ec is visible in +/ec/ec triploids (Gersh). RK1.

Model Confidence:
  • Very high (pLDDT > 90)
  • 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.

                Other Comments

                rst expression and sorting of interommatidial cells are not affected by ec mutations.

                Individuals homozygous for Bpt1 and ec exhibit no Bpt1 phenotype. A low frequency of individuals exhibit the lethal pharate adult phenotype.

                A screen for rough eye mutants identifies ec, ec is required for normal elimination of surplus cells from the retinal epithelium. Cell death eliminates 2 or 3 cells per ommatidium 35 and 50 hours after pupation.
