Imprecise excision of RhoGAP18B1 P-element results in a 625bp deletion in the first RC exon, which is predicted to cause an early termination of the RC ORF.
RhoGAP18BΔRC mutants exhibit resistance to ethanol-induced sedation.
RhoGAP18BΔRC mutant flies exhibit significantly reduced loss-of-righting (LOR-refers to the inability of flies to regain upright posture upon mechanical stimulation) compared to control flies.
Based on resistance to enthanol-induced sedation, the following RhoGAP18B alleles can be ranked from strongest to weakest as follows: RhoGAP18B3 > RhoGAP18B1 = RhoGAP18BΔRC.
