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 screened an A . thaliana cDNA library , whose inserts are under the control of the galactose - inducible GAL10 promoter , for cDNAs which enabled YDH8 cells to grow at the restrictive temperature .
Example Output: GAL10 promoter

Example Input:  Avian EMILIN was extracted from 19 - day - old embryonic chick aortas and associated blood vessels and purified by ion - exchange chromatography and gel filtration .
Example Output: Avian EMILIN

Example Input:  Using unidirectional PCR we isolated a 361 - bp 5 ' promoter region and delineated the intronic / exonic boundaries which include a non - coding exon 1 , a single intron , and a coding exon 2 , a structure that is typical of genes of the RNase A superfamily .
Example Output:
RNase A superfamily
