IRESite record type: plasmid_with_promoter_and_putative_IRES_translationally_characterized
The shape of the nucleic acid molecule translated: linear
The quality of the mRNA/+RNA sequence: hopefully_full-length_mRNA
The mRNA/+RNA description:
Putative in vivo CMV promoter-derived transcript produced from bicistronic plasmid pbetaGAL/XIAP/CAT which
comprises beta galactosidase and chloramphenicol acetyltransferase as the first and the second cistron
respectively and the whole part of human XIAP 5' UTR (nt from -993 to nt -1 of the original sequence) mRNA
cloned between them.
The sequence ends at its 3'-end right after the poly(A) signal from BGH mRNA and thus the 3'-UTR might be
slightly wrong.
The mRNA/+RNA sequence represented in the +DNA notation:
Credibility of mRNA sequence: end-to-end_sequence_reverse_engineered_and_should_match_experiment
The name of the promoter used to express this mRNA: CMV
Aliases of the plasmid name:
Alias: pbetaGAL/hUTR/CAT
Description of the plasmid (facultative for promoter-less plasmid records): Plasmid containing the whole part of human XIAP 5' UTR (nt from -993 to nt -1 of the original sequence)
inserted between beta galactosidase and chloramphenicol acetyltransferase reporter genes.
