UAS regulatory sequences drive expression of Btk29A.
germarium, with Scer\GAL4C587
spectrosome, with Scer\GAL4C587
Expression of Btk29AScer\UAS.cHa under the control of Scer\GAL4C587 leads to the overproduction of spectrosome bearing cells in germaria.
BtkUAS.cHa/Scer\GAL4bab1-GAL4-U rescues Btkfic-P
