Subject: Re: pnrVE12 pnrVE12 and pnrVE13 require a little communication (Schaal, Biryukova & Heitzler) to flybase since they did not appear in previous literature. They were EMS induced and represent new null alleles of pnr, found in a ChipE/+ background as dominant enhancers of ChipE. In both cases they encode a severely truncated protein due to premature stop codon. VE12: R98*. R98 (cga) becomes stop (tga). VE12 encodes a 97 aa isoform A protein and a 45 aa isoform B protein. VE13: Q113*. Q113 (cag) becomes stop (tag). VE13 encodes a 112 aa isoform A protein and a 60 aa isoform B protein. The molecular characterization has been performed (pcr) by Aurelie Schaal during her DUT probationary period in my lab. Both mutants show the severe embryonic dorsal hole phenotype.
