The shape of the nucleic acid molecule translated:

The quality of the mRNA/+RNA sequence:
  3UTR_possibly_incomplete
The mRNA/+RNA description: 
Putative in vivo CMV promoter-derived transcript produced from bicistronic plasmid pbetaGAL/HIAP2(1-990)/CAT
which comprises beta galactosidase and chloramphenicol acetyl transferase as the first and the second cistron
respectively and the part of human c-IAP1 5' UTR (nt from -1222 to nt -233 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.
