Ki values of Ki16425

The Ki values were estimated from inositol phosphate response shown in Fig. 2 (left column) or from the GTPγS binding assay shown in Fig. 3 (right column), in a manner similar to that for the inositol phosphate response for LPA2 and based on the Schild regressions for other receptor subtypes. See more detail under Materials and Methods.
