In this task, you are given a sentence. You are expected to recognize the name of gene or protein. Although there might be several correct answers, you need to write one of them.

[Q]:  Some CHOP - C / EBP heterodimers apparently bind to alternative DNA sequence and thereby regulate the transcription of other genes .
[A]: C / EBP


[Q]:  By sequencing of exonuclease III deletion clones an open reading frame of 405 nucleotides was found coding for a protein of 135 amino acids with a molecular mass of 15 kDa .
[A]: exonuclease III


[Q]:  However , C / EBP beta stimulated transcription primarily through the cAMP - responsive element ( CRE ) , which maps between positions - 77 to - 94 , but not at the more 5 ' - binding sites .
[A]:
C / EBP
