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: We now describe a HepG2 cell casein kinase II beta subunit cDNA of 2 . 57 kb containing 96 bases of 5 ' untranslated sequence , 645 bases of open reading frame , and 1832 bases of 3 ' untranslated sequence with two polyadenylation consensus signal sequences and two poly ( A ) stretches .

Output: casein kinase II

Input: Consider Input: Multiple attempts aimed at disruption of the chromosomal fabG gene were unsuccessful .

Output: chromosomal fabG gene

Input: Consider Input: Our results are consistent with TCOF1 mutations leading to the Treacher Collins syndrome phenotype .
Output: TCOF1 mutations
