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:  Protease digestion and alkaline extraction of microsomes containing labeled mutant proteins further showed that segment 3 was sufficient for stable membrane anchoring of the glycoproteins , indicating that this segment may specify the transmembrane domain of the gB glycoprotein .
Example Output: gB glycoprotein

Example Input:  Three experiments using 20 microM 2 - ( hydroxyamino ) - 1 - methyl - 6 - phenylimidazo [ 4 , 5 - b ] pyridine ( N - OH - PhIP ) were performed to induce mutations in the dihydrofolate reductase ( DHFR ) gene of a hemizygous Chinese hamster ovary ( CHO ) cell line ( UA21 ) .
Example Output: dihydrofolate reductase

Example Input:  The gene atp6 , encoding subunit 6 of the mitochondrial F0 - ATPase complex , has been characterized from both the normal ( fertile ) and Ogura ( male - sterile ) radish cytoplasms in order to determine if previously identified atp6 transcriptional differences could play a role in cytoplasmic male sterility .
Example Output:
gene atp6
