Is predicted to encode a protein with the following domains: PH-like domain superfamily; PDZ superfamily; PTB/PI domain; PDZ domain; and Phosphotyrosine interaction domain (PTB/PID). Is an ortholog of C. elegans lin-10. In C. elegans, lin-10 is involved in several processes, including neuron-neuron synaptic transmission; positive regulation of backward locomotion; and protein localization.
