Probably not involved in maintaining the position of ASI and ASH head neuron cell bodies and ventral nerve cord axons of PVQ, PVP, RMEV, AVK and HSN neurons. Expressed in neurons and body wall muscles. Expression begins at the late L1 larval stage. No visible phenotype (PubMed:19737747, PubMed:22829780). No defect in the positioning of ASI and ASH neuron cell bodies (PubMed:22829780). No defect in the positioning of PQV, PVP, RMEV, HSN adn AVK axons in the ventral nerve cord (PubMed:19737747). In a zig-2, zig-3, zig-4 or zig-5 or zig-8 mutant background, cell body positioning of ASI and ASH head neurons is normal (PubMed:22829780).
