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:  It also showed which amino acid residues would contact an extended TATA box with a B recognition element , and evolutionary conservation of the TBP - TFB - DNA complex orientation between two archaeal organisms with widely different optimal temperature for growth ( 37 and 100 degrees C ) .
Example Output: B recognition element

Example Input:  This complex was eliminated by mutation of either half - site , and it was supershifted by antibodies against chicken ovalbumin upstream promoter - transcription factor ( COUP - TF ) .
Example Output: COUP - TF

Example Input:  Dominant - negative upf1 mutations were isolated following in vitro mutagenesis of a plasmid containing the UPF1 gene .
Example Output:
UPF1 gene
