hkb | Huckebein (hkb) is expressed in patches within the embryonic neuroectoderm and a subset of neuroblasts and their progeny, where it is required for proper neuronal specification and axon targeting. It is a terminal gap gene mediating the maternal terminal information at the posterior end of the blastoderm embryo. (297 aa) | ||||
tra | Female-specific protein transformer; Member of the regulatory pathway controlling female somatic sexual differentiation, regulated by Sxl. Activates dsx female-specific splicing by promoting the formation of a splicing enhancer complex which consists of tra, tra2 and sr proteins. Together with tra-2, plays a role in switching fru splicing from the male-specific pattern to the female-specific pattern through activation of the female-specific fru 5'-splice site. No known function in males. (197 aa) |
