UASt regulatory sequences drive expression of the Hsap\NR2F1 open reading frame. The ORF was obtained from the human ORFeome v7.1 collection ( ORF_ID:5386 ) and corresponds to Ensembl transcript ENST00000327111.7. The endogenous stop codon is present, thus even though three copies of the Tag:HA tag are present downstream of the ORF, they are not expected to form part of the translated protein.
