A Tag:V5 epitope has been introduced into the endogenous zld locus, such that is tags the C-terminal end of the RB isoform.
Sequences encoding the V5 epitope (GKPIPNPLLGLDST) are inserted between the indicated bases just before the zld stop codon (isoform-specific). Created as a tag for zld-RB but should also affect the zld-RA and zld-RG isoforms.
