Cytology
Description

The FRT cassette present in TI{TI}tkvGFP.FRT.M442T-mCh has been excised, removing the GFP-tagged wild-type tkv coding sequence and allowing expression of the mutated mCherry-tagged tkv coding sequence that remains; this mutated sequence carries a M470T change in the orthologous human BMPR1A gene, a variant identified in patients with Juvenile polyposis syndrome).
