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.

Example Input:  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 .
Example Output: C / EBP

Example Input:  Whereas mutant 6C4 specified a wild - type - size Pol protein , we detected no full - length Pol protein in 7E4 - infected cell extracts .
Example Output: mutant 6C4

Example Input:  RESULTS : Although low levels of vIRF - 2 mRNAs can be detected in the HHV - 8 - positive BCBL - 1 tumor cell line , 12 - 0 - tetradecanoylphorbol - 13 - acetate ( TPA ) treatment does not stimulate expression of vIRF - 2 gene together with primary lytic cycle genes .
Example Output:
vIRF - 2
