The coding region of cDNA clone FI18815 was PCR amplified and cloned in frame into pENTR4 (HiFi assembly, NEB) and then into pPHW using Clonase (Life Tech.). The target sequence for GL00409 is located in the 5’UTR of Cenp-C and, therefore, this transgene is RNAi resistant. The GFP-CENP-C transgenes were constructed by Christian Lehner and contain the 5’UTR sequences upstream of the GFP sequence, and thus is RNAi sensitive. MIS12 localization was observed using a UASP regulated GFP-fusion transgene [65 (link)].
