25825713 Data show that two lysine residues that are unique to the N terminus of calcium-activated potassium channel subunit beta-1 were identified to be sufficient for voltage-sensor modulation.
25576871 To determine the relationship between atherosclerosis and KCNMB1, we studied some atherogenic factors affecting vascular tone. Blood of atherosclerotic patients shows increased concentration of 7-ketocholesterol, possibly a harmful lipid to blood vessels.
25275635 The study demonstrates that both transmembrane domains of BKbeta1 are required to provide the characteristic ion current phenotype of beta1-containing BK channels.
24569989 N-terminal isoforms of the large-conductance Ca(2)-activated K channel are differentially modulated by the auxiliary beta1-subunit.
24476761 Bisphenol A activates BK alpha via an extracellular site and that Bisphenol A-sensitivity is increased by the beta1 subunit.
23825428 In large-conductance calcium-dependent potassium channels, beta1 and beta2 subunits alter the voltage sensing domain-cytosolic domain interface.
23255603 The results indicate that the beta1-subunit can form a tripartite complex with TP and MaxiKalpha, has the ability to associate with each protein independently.
22114151 HIF-1alpha increases KCNMB1 expression in response to hypoxia in human pulmonary artery smooth muscle cells by binding to two hypoxia response elements located at -3,540 to -3,311 of the KCNMB1 promoter
21413024 Cloned BK(Ca) channel directly regulated apoptosis and proliferation of HEK293 cell under hyperglycemia condition.
20966391 downregulation of vascular BK-beta(1) expression in diabetes and in high-glucose culture conditions was associated with FOXO-3a/FBXO-dependent increase in BK-beta(1) degradation.
