Figure 1. Ca2+ dependencies of types 1 and 3 InsP3R channel Po in the presence of 0.5 mM ATP. 10 μM InsP3 was present in the pipet solutions used in experiments presented in all figures. Open triangles represent data for X-InsP3R-1 obtained from uninjected oocytes. Closed squares represent data for r-InsP3R-3 obtained from cRNA-injected oocytes. The curves (dashed for X-InsP3R-1 and solid for r-InsP3R-3) are the biphasic Hill equation fits from Mak et al. 2001.
