Scer\GAL4c527-mediated expression of Mmp2E258A.Scer\UAS results an elongated ventral nerve cord. There is no loss of the ECM, but a rather wrinkled appearance.
Scer\GAL4elav.PU-mediated expression of Mmp2E258A.Scer\UAS results in aberrant ISNb morphology - defasciculation with loose bundling and ectopic branches. Scer\GAL4repo.PU-mediated expression has similar effects but with increased penetrance.
