The RMCE cassette of the TI{CRIMIC.TG4.0}CG2772CR02306-TG4.0 insertion has been replaced with a TI{FFL.0} cassette that is in gene-trap (GT) orientation relative to CG2772. This is expected to truncate the CG2772 protein and to result in the expression of a separate mCherry protein under the control of endogenous CG2772 regulatory sequences.
