| 44039 | Q9VI13 | PAK_DROME | Serine/threonine-protein kinase Pak (EC 2.7.11.1) | DISRUPTION PHENOTYPE | Homozygous knockout flies show defective wing morphology. Mutant embryos show guidance phenotypes in ventral oblique muscle 5 (VO5), ventral oblique muscle 6 (VO6) and ventral acute muscle 3 (VA3). The affected muscles bypass their normal ventral attachment sites and mistarget toward or crossing the ventral midline. Mutant embryos exhibit additional muscle phenotypes, such as increase in lateral transverse (LT) muscles and VA3 numbers and defective lateral oblique muscle 1 (LO1) and ventral oblique muscle 1 (VO1) shape. {ECO:0000269|PubMed:18996366}. |
