22560931 Expression of Kv1.4 appears to increase in the spinal cord of mice modelling remitting-relapsing experimental allergic encephalomyelitis (rrEAE) in peak and remitting phases.
21945024 Detection of the methylation prevalence of KCNA4 and CYP26B1 together in serum demonstrated the good sensitivity and specificityin gastric cancer
21307345 Data suggest that episodic ataxia type 1 mutations affect fast inactivation of Kv1.1/1.4 channels by a reduction in either subunit surface expression or altered affinity for the inactivation domain.
19961828 Sialylated N-glycans uniquely impact gating of a mammalian Shaker family K(v) channel isoform, K(v)1.5, but have no effect on gating of a second Shaker isoform, K(v)1.4.
19453640 Both arachidonic acid and Trolox potently modulate Kv1.4 and Kv4.2 channel alpha-subunits, thereby presumably tuning presynaptic transmitter release and postsynaptic somatodendritic excitability in synaptic transmission and plasticity.
18640987 Thr-330 of Kv1.4 serves to interlock the voltage-sensing and gating domains of adjacent monomers, thereby yielding a structure competent for the surface expression of functional tetramers
17959711 Ginsenoside Rg3 inhibits KV1.4 channel currents by interacting with the lysine531 residue.
17156368 The results demonstrate that the human Kvbeta1.1 and Kvbeta1.2 subunits regulate the proportion of wild-type Kv1.4-1.1 channels that are available to open.
16308273 Fast inactivation in human Kv1.4 is modulated by structural elements in the C-terminus, suggesting that the process involves the concerted action of the N- and C-termini.
15955806 Novel role for GIP in regulating K(V)1.4 cell surface expression and modulation of A-type potassium currents
15136567 Results describe an erbstatin (Erb) analogue as a small molecule inhibitor of the N-type inactivation in potassium channels Kv1.4 and Kv1.1+Kvbeta1.
12065763 N-type inactivation in hKv1.4 is regulated by pH(i) in the physiologic range through ionization of specific amino acid residues in the ball domain.
