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.

Q:  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 .

A: gene atp6
****
Q:  Detailed analysis of the predicted amino acid sequence revealed sequence elements which are conserved in many DNA and RNA polymerases .

A: RNA polymerases
****
Q:  Immunoprecipitation of cell lysates with anti - phosphotyrosine and immunoblotting showed phosphorylated forms of the mitogenic pathway proteins Shc and MAPK in addition to p185 ( neu ) , suggesting that the Ras to MAPK mitogenic pathway is activated .

A:
anti - phosphotyrosine
