常見問題列表
生物活性
Gap 26 是一種連接蛋白模擬肽，由連接蛋白connexin 43 (Cx43)的細(xì)胞外環(huán)1的殘基 no. 63-75組成，是 gap junction 的抑制劑。Gap 26 可阻止光解inositol-1,4,5-trisphosphate觸發(fā)的ATP釋放。靶點(diǎn)

體外研究
Gap 26 (0.25 mg/mL, 30 min) reduces the wave size in the three cell lines (RBE4, SV-ARBEC and ECV304). Gap 26 (0.25 mg/mL, 30 min) completely abolishes the InsP3-triggered ATP response and reduced the ATP release to below the control level, indicating that the basal ATP release is also affected.
Gap 26 does indeed significantly inhibit our InsP3-triggered intercellular calcium waves, but it did not have any effect on dye coupling through junctional channels as evidenced by the FRAP experiments, despite the fact that connexin 43 was present in the cell lines used.
Gap 26 (100-300 μM) dose-dependently reduces the rhythmic responses of rabbit superior mesenteric arteries, with IC
50
of 28.4 ± 3.4 μM.
