Previous genetic studies defined a cascade of negatively interacting genes that regulates tra-1 activity in response to the primary sex-determining signal. Here, we investigate the last step in this regulatory cascade, by studying rare gain-of-function (gf) mutations of tra-1 that direct female somatic development irrespective of the upstream sex-determining signal. These mutations appear to abolish negative regulation of tra-1 in male tissues. We identify the lesions associated with 29 of these mutations and find that all affect a short stretch of amino acid residues present in both protein products of the tra-1 gene. Twenty-six alleles are associated with single nonconservative amino acid substitutions. Two alleles affect tra-1 RNA splicing and generate messages that omit part or all of the exon encoding this short stretch. These results suggest that sexual regulation of tra-1 is achieved post-translationally, by an inhibitory protein-protein interaction. The amino acid stretch altered by the tra-1(gf) mutations may define a site of interaction for negative regulators of tra-1. The stretch includes a potential phosphorylation site for glycogen synthase kinase 3 and may be conserved in the human gene GLI3, a homolog of tra-1 identified previously.","lang":"eng"}],"intvolume":"         9","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87"}
