Contains endogenous lqf regulatory sequences (the same as those present in lqfFL.GFP) and the following regions of the lqf coding sequence: the lqf Epsin N-terminal homology (ENTH) domain, Ubiquitin interaction motif (UIM) 1 and four copies of the Clathrin binding motif (CBM). A GFP tag is present at the C-terminal end of the coding sequence.
