靶點(diǎn)詳情

  • 功能：
    Regulatory subunit of the calcium activated potassium KCNMA1 (maxiK) channel. Modulates the calcium sensitivity and gating kinetics of KCNMA1, thereby contributing to KCNMA1 channel diversity. Increases the apparent Ca(2+)/voltage sensitivity of the KCNMA1 channel. It also modifies KCNMA1 channel kinetics and alters its pharmacological properties. It slows down the activation and the deactivation kinetics of the channel. Acts as a negative regulator of smooth muscle contraction by enhancing the calcium sensitivity to KCNMA1. Its presence is also a requirement for internal binding of the KCNMA1 channel opener dehydrosoyasaponin I (DHS-1) triterpene glycoside and for external binding of the agonist hormone 17-beta-estradiol (E2). Increases the binding activity of charybdotoxin (CTX) toxin to KCNMA1 peptide blocker by increasing the CTX association rate and decreasing the dissociation rate.

    1. Whole-cell currents density of BK channels and amplitude of spontaneous transient outward currents were significantly reduced in hypoxia vascular myocytes. PMID: 29486465
    2. Study showed that in human and rat arterial myocytes, membrane depolarization rapidly increased the cell surface abundance of auxiliary BK beta1 subunits but not that of the pore-forming BKalpha channels. Membrane depolarization stimulated voltage-dependent Ca(2+) channels, leading to Ca(2+) influx and the activation of Rho kinase (ROCK) 1 and 2. PMID: 28487419

    20. the beta1-subunit of BK(Ca) contributes to the increased glomerular filtration rate that accompanies an acute salt and volume load and raises the possibility that it is also involved in regulating K(+) excretion under these conditions PMID: 12620927
    21. BK channels have a central role in urinary bladder function PMID: 15184377
