Abstract:
Many non-catalytic cellular proteins exert biological functions by formation of stable or transient complexes with other proteins. Analysis of the signal-induced physical interactions is important to understand their physiological roles in cells. Here we describe a biochemical method for assessing the binding of ALG-2 (gene name, PDCD6) to its target proteins that are immunoprecipitated from cell lysates. Application of nanoluciferase (Nluc)-fused ALG-2 enables a rapid quantitative evaluation of Ca2+-dependent interactions of target proteins with ALG-2 in vitro binding assays.
