The RMCE cassette of the TI{CRIMIC.TG4.2}CG2616CR60280-TG4.2 insertion has been replaced with a TI{FFL.2} cassette that is in gene-trap (GT) orientation relative to CG2616. This is expected to truncate the CG2616 protein and to result in the expression of a separate mCherry protein under the control of endogenous CG2616 regulatory sequences.
