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.

Input: Consider Input:  In contrast , vaccination with a peptide encoding an adenovirus type 5 ( Ad5 ) E1A CTL epitope results in CTL tolerance and enhanced growth of an Ad5 E1A - expressing tumor .

Output: Ad5 E1A


Input: Consider Input:  Therefore , under appropriate experimental conditions , it was possible to demonstrate cross - reactivity between the antiserum against rat liver glucocorticoid receptor and the 58 - to 62 - A ( Stokes radius ) glucocorticoid receptor from species as diverse as mouse and humans .

Output: glucocorticoid receptor


Input: Consider Input:  In glucocorticoid - sensitive cells [ 3H ] CVZ causes a 2 - fold induction of glutamine synthetase and binds to a protein in the 4 . 6 S region of high salt sucrose gradients .


Output: glutamine synthetase
