Is predicted to encode a protein with the following domains: PH-like domain superfamily; Phosphotyrosine interaction domain (PTB/PID); PTB/PI domain; PDZ superfamily; and PDZ domain. 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.
