D-myo-Inositol-1,2,5,6-tetraphosphate (Ins(1,2,5,6)P4) is one of the many inositol phosphate isomers that act as small, soluble second messengers in the transmission of cellular signals.1,2,3. Ins(1,2,5,6)P4 binds to the murine Grp-1 PH domain with a Kd(apparent) of 0.18 µM, which is about 6.7-fold higher than for Ins(1,3,4,5)P4.4 It binds to rat heart membranes and significantly decreases heart rate in a pithed rat model.5
