CPTI: Cambridge Protein Trap Insertion

CPTI, YFP fusion protein expression lines:

Created by UK laboratories using a hybrid piggyBac/P-element protein trap construct with 3xFLAG-Strep-venus-Strep containing

  • Splice acceptor and donor sites
  • Two affinity purification tags (StrepII and FLAG)
  • A functional Venus YFP exon

Constructs are PIGP3{SVS-A} (601) and PIGP3{FSVS-A} (681). Lineages of protein trap constructs are found at a FlyProt page:
