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:  We have utilized transient transfections , mutation analysis , electromobility gel - shifts , and immunoblot analysis to test the hypothesis that expression of the CTalpha gene is controlled in part by the binding of three trans - acting nuclear factors , Sp1 , Sp2 , and Sp3 .
Example Output: CTalpha gene

Example Input:  The elevated levels of inositol phosphates resulting from N ( epi ) alpha qQ209L expression were similar to those obtained with carbachol activation of the M1 muscarinic acetylcholine receptor .
Example Output: acetylcholine receptor

Example Input:  Treatments were two adrenocorticotrophin ( ACTH ) preparations given intramuscularly at 2 . 2 U / kg , one of the ACTH preparations given intramuscularly at 1 U / kg and a synthetic polypeptide with ACTH - like activity ( tetracosactrin , cosyntropin ) given intravenously at 5 micrograms / kg .
Example Output:
ACTH - like
