The RMCE cassette of the TI{CRIMIC.TG4.0}CG7220CR00896-TG4.0 insertion has been replaced with a TI{FFL.0} cassette that is in gene-trap (GT) orientation relative to CG7220. This is expected to truncate the CG7220 protein and to result in the expression of a separate mCherry protein under the control of endogenous CG7220 regulatory sequences.
