Allen et al., "The SINE-encoded mouse B2 RNA represses mRNA transcription in response to heat shock," Nat Struct Mol Biol, 11:816–21, September 2004.A small, noncoding RNA, called B2, is expressed during heat shock and represses transcription from RNA polymerase II. Interestingly, B2 RNA is transcribed from a DNA region previously thought to
