Mask promotes normal NMJ terminal growth by affecting motor neuron MT stability. (A) Confocal images (representative of three experiments) of NMJs of larval muscle 4 in wild type, mask null (mask^10.22/Df), mask null rescued with a UAS-Mask transgene driven by pan-neuron (BG380), ubiquitous (DA) or muscle (MHC) Gal4 drivers, and stathmin;mask double mutant (stai^B200/L27; mask^10.22/Df). Scale bar: 10 µm. (B) Quantification of the number of boutons, synaptic span and branching points at the muscle 4 NMJs. Each data point was normalized to the size of the imaged muscle 4.
