UASt regulatory sequences drive expression of a 500bp inverted repeat.
Expression of FAM21NIG.16742R under the control of Scer\GAL4VP16.mat.αTub67C leads to premature ooplasmic streaming in stage 7 oocytes, disorganized actin at the oocyte cortex and ring canals surrounded by diffuse actin structures in stage 7-9 egg chambers when compared to controls.
