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.

Ex Input:
The proteins encoded by these genes , called GF14 proteins , participate in protein / DNA complexes and show more than 60 % identity with a highly conserved , widely distributed protein family , collectively referred to as 14 - 3 - 3 proteins .

Ex Output:
GF14 proteins

Ex Input:
The highly conserved region of U6 snRNA has a structural similarity with the catalytic domain of the negative strand of the satellite RNA of tobacco ring spot virus [ ( - ) sTRSV ] , suggesting that the highly conserved region of U6 snRNA forms the catalytic center .

Ex Output:
U6 snRNA

Ex Input:
The enzyme ACC oxidase catalyses the last step of ethylene biosynthesis in plants , converting 1 - aminocyclopropane - 1 - carboxylic acid ( ACC ) to ethylene .

Ex Output:
enzyme ACC oxidase
