The FERM-PTPs are a group of proteins that have FERM (Band 4.1, ezrin, radixin, moesin homology) domains at or near their N-termini, and PTP (protein tyrosine phosphatase) domains at their C-termini. Their central regions contain either PSD-95, Dlg, ZO-1 homology domains or putative Src homology 3 domain binding sites. The known FERM-PTPs fall into three distinct classes, which we name BAS, MEG, and...
There are several mechanisms for the determination of sex. Sexual behaviour is part of the sex-determination cascade, and in Drosophila melanogaster male courtship is controlled in part by the fruitless gene. As part of a study of sexual behaviour in Hawaiian Drosophila, we have cloned the neural sex-determination gene fru from the Hawaiian picture-wing species Drosophila heteroneura. The fru gene...
We characterized molecular profiles of a new olfactory mutant line, honoka (hono), which was found among 500 viable P-element insertion lines screened first by 5-bromo-4-chloro-3-indrolyl-β-d-galactopyranoside (X-gal) staining on the third segment of the antenna, and then by behavioral assays to several pure chemicals.The behavioral responses of hono mutants to repellents such as ethyl acetate (EA),...
