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: 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

Example Input: Toxicity of benzoyl chloride ( 2 , 4 , 6 - trichlorophenyl ) hydrazone ( Banamite ) and potential metabolites to twospotted spider mites and potency as inhibitors of rat liver monoamine oxidase .
Example Output: monoamine oxidase

Example Input: On the basis of experiments with mutant virus and transfection with isolated genes , the herpes simplex virus immediate - early gene product ICP4 is known to positively regulate the transcription of viral early and late genes and negatively regulate expression from its own promoter .
Example Output:
early gene
