Interestingly, the cloned TCF-1 alpha protein is a potent transcriptional activator of the human TCR alpha enhancer in nonlymphoid cell lines , whereas the activity of the endogenous protein in T cell lines is strongly dependent on an additional T cell-specific protein that interacts with the core enhancer .
 protein: transcriptional activator; DNA: core enhancer; DNA: human TCR alpha enhancer; cell line: nonlymphoid cell lines; cell line: T cell lines; protein: TCF-1 alpha; cell line: T cell-specific protein; protein: endogenous protein; protein: TCF-1 alpha protein
