''BTB3-AS1'' is an antisense transcript of ANA/BTG3. it is a highly conserved gene encoded by the DNA strand opposite the ANA/BTG3 gene.
 
  
 
===Function===
 
===Function===
In ovarian carcinoma, ''BTB3-AS1'' promotes tumorigenesis through suppressing translation of the sense gene (ANA/BTG3) <ref name="ref1" />. ''BTB3-AS1'' forms duplexes with ANA/BTG3 mRNA in the nucleus and suppresses its cytoplasmic transportation, leading to negative regulation of ANA/BTG3 at protein level without changing of its mRNA level <ref name="ref1" />.

''DEC1'' cDNA can suppress growth of some cancer cells in vitro, it is a candidate tumor suppressor in 9q32 <ref name="ref1" />.
''BTB3-AS1'' also plays a key role in Wnt/β-catenin-mediated tumorigenesis <ref name="ref2" />. ''BTB3-AS1'' interacts with and recruits transcription factor 3 (TCF3) for activating transcription factor 3 (ATF3) locus and represses the expression of ATF3, resulting in proliferation and tumorigenicity of colon tumor cells <ref name="ref2" />.
