2-aminoethoxydiphenyl borate is a common activator of TRPV1, TRPV2, and TRPV3.
The transient receptor potential (TRP) superfamily contains a large number of proteins encoding cation permeable channels that are further divided into TRPC (canonical), TRPM (melastatin), and TRPV (vanilloid) subfamilies. Among the six TRPV members, TRPV1, TRPV2, TRPV3, and TRPV4 form heat-activated cation channels, which serve diverse functions ranging from nociception to osmolality regulatio...
متن کاملBiphasic currents evoked by chemical or thermal activation of the heat-gated ion channel, TRPV3.
2-Aminoethyl diphenylborinate was recently identified as a chemical activator of TRPV1, TRPV2, and TRPV3, three heat-gated members of the transient receptor potential vanilloid (TRPV) ion channel subfamily. Here we demonstrated that two structurally related compounds, diphenylboronic anhydride (DPBA) and diphenyltetrahydrofuran (DPTHF), can also modulate the activity of these channels. DPBA act...
متن کاملInhibition of the human epithelial calcium channel TRPV6 by 2-aminoethoxydiphenyl borate (2-APB).
TRPV6, a highly calcium-selective member of the transient receptor potential (TRP) channel superfamily, is a major pathway for calcium absorption in the fetal and adult body. It is expressed abundantly in the duodenum, the placenta and exocrine tissues. TRVP6 was postulated to contribute to store-operated calcium channel (SOC) activity in certain cell types such as exocrine cells. In this study...
متن کامل2-Aminoethoxydiphenyl borate activates the mechanically gated human KCNK channels KCNK 2 (TREK-1), KCNK 4 (TRAAK), and KCNK 10 (TREK-2)
Two-pore domain K(+) (KCNK, K2P) channels underlie the "leak" (background) potassium conductance in many types of excitable cells. They oppose membrane depolarization and cell excitability. These channels have been reported to be modulated by several physical and chemical stimuli. The compound 2-aminoethoxydiphenyl borate (2-APB) was originally described as an inhibitor of IP3-induced Ca(2+) re...
متن کاملBlock of specific gap junction channel subtypes by 2-aminoethoxydiphenyl borate (2-APB).
2-Aminoethoxydiphenyl borate (2-APB), an inositol 1,4,5-triphosphate receptor modulator, inhibits capacitive current transients measured in normal rat kidney and human embryonic kidney 293 cells, an indication of blocking gap junction channels between these cells. Here, we used the dual whole-cell patch-clamp method to study the actions of 2-APB on gap junction channels formed by selected conne...
