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 have previously observed that ionizing radiation induces tyrosine phosphorylation in human B - lymphocyte precursors by stimulation of unidentified tyrosine kinases and this phosphorylation is substantially augmented by vanadate .

Output: tyrosine kinases


Input: Consider Input:  This sequence - specific binding is probably mediated by a highly conserved sequence motif , ATTTGCAT , present in all three transcriptional elements .

Output: transcriptional elements


Input: Consider Input:  In electrophoretic mobility shift assays , an oligonucleotide containing kappa 3 forms two DNA protein complexes with proteins that are present in extracts from unstimulated T cells .


Output: kappa 3
