The RMCE cassette of the TI{CRIMIC.TG4.2}Ca-Ma2dCR01742-TG4.2 insertion has been replaced with a TI{FFL.2} cassette that is in gene-trap (GT) orientation relative to Ca-Ma2d. This is expected to truncate the Ca-Ma2d protein and to result in the expression of a separate mCherry protein under the control of endogenous Ca-Ma2d regulatory sequences.
