The RMCE cassette of the TI{CRIMIC.TG4.2}CG1371CR00885-TG4.2 insertion has been replaced with a TI{FFL.2} cassette that is in gene-trap (GT) orientation relative to CG1371. This is expected to truncate the CG1371 protein and to result in the expression of a separate mCherry protein under the control of endogenous CG1371 regulatory sequences.
