CC   -!- FUNCTION: Member of the regulatory pathway controlling female somatic
CC       sexual differentiation, regulated by Sxl. Activates dsx female-specific
CC       splicing by promoting the formation of a splicing enhancer complex
CC       which consists of tra, tra2 and sr proteins.
CC       {ECO:0000269|PubMed:1592233}.
CC   -!- SUBCELLULAR LOCATION: Nucleus speckle {ECO:0000250}. Note=Speckled
CC       subnuclear compartment. {ECO:0000250}.
CC   -!- DOMAIN: RS domain directs localization of proteins to the speckled
CC       subnuclear compartment and the purpose of this localization is to allow
CC       colocalization and co-concentration of components of the splicing and
CC       splicing regulatory machinery to permit relatively high rates and/or
CC       efficiencies of reaction and interaction. {ECO:0000250}.
CC   -!- MISCELLANEOUS: The sexual regulation of tra occurs through a mechanism
CC       of sex-specific alternative RNA splicing. The non-sex-specific RNA
CC       expressed in males is not translated.
