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:  RESULTS : Consistent with the known features of nasal polyps , CD4 + ( T helper / inducer ) , CD8 + ( cytotoxic / suppressor ) , CD68 + ( macrophages ) , mast cells , eosinophils and neutrophils were all clearly detected by their relevant monoclonal antibodies or appropriate histochemical staining , but only mast cells tested positive for ER / PR labelling with their polyclonal and monoclonal antibodies .

Output: monoclonal antibodies


Input: Consider Input:  Deficiencies in the gene for this dual functional protein result in hyperphenylalaninemi .


Output: dual functional protein
