2-APB is a transient receptor potential (TRP) activator. The compound also directly blocks the mitochondrial permeability transition pore, sarco/endoplasmic reticulum Ca2+-ATPase pumps, and native store operated channels, as well as other ion channels. 2-APB does not activate the subfamily transient receptor potential vanilloids (TRPVs) TRPV4, TRPV5, and TRPV6, but can activate VR1 (TRPV1), VRL-1 (TRPV2), and TRPV3. 2-ABP was first used as an inhibitor of IP3R (inositol 1,4,5-triphosphate receptor) with the ability to permeate the membrane. 2-ABP can induce Ca2+entry without activating exocytosis. In pancreatic acinar cells 2-ABP can inhibit calcium mobilization. 2-APB is an activator of Orai3.

Rated 5 out of 5 by from Kondo Kondo, et. al. (PubMed ID 15551003) found that by treating their samples 30 minutes prior to exposure to cockroach extract with the compound 2-APB that the calcium response was inhibited. In addition, this inhibition is demonstrated in a concentration based manner, that is - the level of inhibition is dependent on how much 2-APB was used. -SCBT Publication Review
