Results in enhances preference and sensitivity to ethanol (PubMed:28607459). Fails to develop tolerance to repeated ethanol exposures (PubMed:28607459). Increases axon length and axon branching (PubMed:31718774). RNAi-mediated knockdown increases axon length and axon branching (PubMed:31718774). RNAi-mediated knockdown in a subset of lamina neurons results in axonal swellings and disorganized axonal microtubules (PubMed:31718774). {ECO:0000269|PubMed:28607459, ECO:0000269|PubMed:31718774}. |
