May act as transcription activator (By similarity). Plays a role in neurogenesis by regulating neurite pruning between left and right AIM neurons and left and right RIF neurons during larval development (PubMed:16139210, PubMed:19561603). Regulates olfactory plasticity (PubMed:19561603). Expressed in AIM, RIC, AIZ, ADF, ADL, ASK, AWA, AUA, AIN, RIH (or RIR) and RIF head neurons and, in PVP, PVQ and DVA (or DVC) tail neurons, some intestinal cells, somatic gonad and vulva. Expressed at the comma stage and throughout larval stages and in adult. The left and right AIM neurons and the left and right RIF neurons are connected by abnormal neurites in 40% and 80% of adults respectively (PubMed:16139210, PubMed:19561603). Fails to reduce chemotaxis to benzaldehyde after pre-exposure to benzaldehyde (PubMed:19561603). In mbr-1 and cam-1 double mutants, normal neurite pruning between left and right AIM neurons is restored (PubMed:19561603).
