Input: Consider Input:  Since RIP140 generally down - regulates receptor activity in mammalian cells and specifically down - regulates coactivation mediated by SRC - 1 , we propose a model in which RIP140 indirectly regulates nuclear receptor AF - 2 activity by competition for coactivators such as SRC - 1 .

Output: SRC - 1


Input: Consider Input:  With this study , a total of 13 operators for the glp regulon have been characterized .
