Control of doublesex alternative splicing by transformer and transformer-2 in Drosophila. Autosomal sex-determining system of the housefly: discovery of the first-chromosomal male factor in Kitakyushu, Japan. Cook JM a. PLoS Biol. Together with our finding that csd is not employed to direct the processing of fem in late larvae and pupae, we conclude that an additional mechanism of regulation exists to maintain fem processing into the productive female mode in these late stages.
