ZF-degron, GFP, and 3xFLAG tags inserted into endogenous tpxl-1 locus. No overt phenotypes in a zif-1(gk117) background. GFP expression is observed in microtubules. Presence of ZF-degron targets tagged proteins for ZIF-mediated degradation. Expression of ZIF-1 causes the tagged TPXL-1 protein to be degraded.
