Description

17 nucleotide deletion, between nucleotides 1729 and 1745, causing a frameshift stop truncating the protein to 513 amino acids, and removing the putative α-helices.

Detailed Description
Statement
Reference

Heterozygotes occasionally lack one dorsocentral bristle.

pnrVX4/+ flies occasionally lack one dorsocentral bristle.

Lethality occurs at larval or early pupal stages. Heterozygotes occasionally lack one dorsocentral bristle. Heterozygotes with pnrV1 are viable.

Heterozygotes are missing one of the two dorsocentral bristles. Homozygous clones of cells are missing one or both bristles. Dominant phenotype enhanced in viable transallelic combinations with pnrVX1. Homozygotes die as young larvae with no obvious mutant phenotype.

Reference

Bxhdp-n60/Y ; pnrVX4/+ flies show a severe loss of dorsocentral bristles (significantly more loss is seen than in pnrVX4/+ flies).

sensE2/pnrVX4 double heterozygotes show loss of dorsocentral bristles.

pnrVX4/CtBPrev19 flies show an increase in the number of dorsocentral bristles.
