Mutations that disrupt both smg recognition elements (SREs) in the nos 3'UTR. The first SRE is within TCE stem loop II and the second SRE is located within the 3' UTR downstream of the TCE.
abnormal neuroanatomy | third instar larval stage
larval multidendritic class IV neuron | third instar larval stage
Third instar larvae expressing nosgnosSREs- show a significant reduction in terminal dendritic branching of the class IV da neurons.
