IRESite record type:
  promoter-less_plasmid_with_putative_IRES
The name of the plasmid:
(deltaCMV)betaGAL/5'(-162)/CAT
Description of the plasmid (facultative for promoter-less plasmid records):
Part of the 5' UTR from human XIAP mRNA (from nt -165 to nt -1 of the original sequence) has been cloned between the beta galactosidase and chloramphenicol acetyl transferase reporter genes. This promoter-less variant of pbetaGAL/5'(-162)/CAT (IRESite ID: 486) was prepared by removing the CMV promoter using NruI and HindIII restriction sites.
The in vivo produced transcripts are heterogeneous (due to any of promoter?/splicing?/cleavage?/breakage?):

Remarks:
XIAP IRES represents part of XIAP 5' UTR (nt from -165 to nt -1 of the original sequence). This region
retained full IRES activity comparable with the whole 5' UTR (from nt -993 to nt -1) of XIAP mRNA.
