Two pp56(lck) mutants lacking either the entire catalytic domain or the entire NH2 regulatory domain were generated, and their abilities to trigger transactivation of the TCR-regulated nuclear factor of activated T cells ( NF-AT ) region of the IL-2 promoter were compared.
 protein: NH2; protein: pp56(lck); DNA: TCR-regulated nuclear factor of activated T cells ( NF-AT ) region; DNA: IL-2 promoter; protein: TCR-regulated nuclear factor; protein: catalytic domain; protein: NF-AT; protein: pp56(lck) mutants; cell type: activated T cells; protein: regulatory domain
Given options, please tell me the categories of all the listed entity words.Output format is "type1: word1; type2: word2". 
Option: cell line, protein, RNA, DNA, cell type
