To define novel proteins involved in the early transcriptional response during the activation of human T lymphocytes , we used a high-resolution, two-dimensional gel electrophoresis system to identify nuclear, deoxyribonucleic acid (DNA) binding proteins exhibiting rapid changes in phosphorylation following cell stimulation.
 ( DNA: deoxyribonucleic acid, None) , ( protein: nuclear, deoxyribonucleic acid (DNA) binding proteins, None) , ( protein: novel proteins, None) , ( cell type: human T lymphocytes, None)
