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:  Furthermore , we have identified the major open reading frame ( RF4 ; 2 . 3 kb ) as being essential for activation , and we have shown that the NF kappa B , SP1 , and TATA box motifs in the human immunodeficiency virus LTR are all required for full induction of the promoter by the HHV - 6 - encoded transactivator .
Example Output: NF kappa B

Example Input:  This mutant also functions in vivo as a trans - acting dominant negative regulator : the transcriptional inducibility of the HIV long terminal repeat ( which contains two potential NF - kappa B binding sites ) by phorbol ester ( PMA ) is inhibited when it is co - transfected into CD4 + T cells with the delta SP mutant .
Example Output: CD4 +

Example Input:  Nonlethal sec71 - 1 and sec72 - 1 mutations eliminate proteins associated with the Sec63p - BiP complex from S . cerevisiae .
Example Output:
sec71 - 1
