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:  Here we show that forced expression of the lung Kruppel - like transcription factor ( LKLF ) in Jurkat T cells is sufficient to program a quiescent phenotype characterized by decreased proliferation , reduced cell size and protein synthesis and decreased surface expression of activation markers .

Output: transcription factor


Input: Consider Input:  Two sequences in the Tip protein were previously shown to be involved in binding to Lck .

Output: Tip protein


Input: Consider Input:  As with the prototypical NF - kappa B p50 - p65 heterodimer , this novel p65 homodimeric form of NF - kappa B is functionally sequestered in the cytoplasm but rapidly appears in the nuclear compartment following cellular stimulation .


Output: p65 homodimeric form
