26005035 Aged patients with sinus rhythm exhibited significantly higher expression levels of HCN2 and HCN4 channel mRNA and protein (P<0.05), but significantly lower expression levels of miR1 and 133, compared with those of adult patients with sinus rhythm.
25423599 N-glycosylation is not required for HCN2 channels to function.
25197093 Data show that Rab8b-interacting protein TRIP8b does not compete with cyclic AMP for the same binding region of hyperpolarization activated cyclic nucleotide gated potassium channel 2 (HCN2).
24525276 Thermal hyperalgesia under chronic inflammatory conditions is mediated by HCN2 channels.
24324597 Novel HCN2 mutation contributes to febrile seizures by shifting the channel's kinetics in a temperature-dependent manner.
23907424 HCN2 polymorphism may play a role in chronic inflammatory periodontitis but not in peri-implantitis.
23395072 LBB-injected HCN2/SkM1 potentially provides a more clinically suitable biological pacemaker strategy than other reported constructs. This superiority is attributable to the more negative AP threshold and injection into the LBB
22131395 This is the first evidence in humans for a single-point, homozygous loss-of-function mutation in HCN2 potentially associated with generalized epilepsy with recessive inheritance.
22094222 HCN2 channels make an important contribution to the maintenance of spontaneous burst activity in embryonic cortical neuron cultures.
21615589 Genetic analysis in 48 Sudden unexpected death in epilepsy cases identified six novel and three previously reported nonsynonymous (amino acid changing) variants in HCN1 , HCN2, HCN3 and HCN4.

18768480 RPTPalpha plays a critical role in HCN channel function via tyrosine dephosphorylation
17931874 Several functional variants were identified including the amino acid substitution R527Q in HCN2 exon 5. HCN2 channels containing the R527Q variant demonstrated a trend towards a decreased slope of the conductance-voltage relation.

17043149 Noise analysis on macroscopic currents revealed fluctuations whose magnitudes were systematically larger than predicted from the actual single channel current size, consistent with cooperativity between single HCN channels.
16777944 With computer modelling, we show that in channels with relatively slow opening kinetics and fast mode-shift transitions, such as HCN2 and HCN4 channels, the mode shift effects are not readily observable, except in the tail kinetics.
15980171 an intact F-actin cytoskeleton is a prerequisite for the swelling-induced HCN2 current
15961404 Mutations of a putative cyclic-nucleotide-binding domain (CNBD) can disrupt the function of the hyperpolarization-activated cyclic-nucleotide-gated channel (HCN2).
15932727 Observational study of gene-disease association. (HuGE Navigator)
15687126 Native I(f) channels in atrial myocardium are heteromeric complexes composed of HCN4 and/or HCN2.
12890777 HCN1 and HCN2 expression were measured using in situ hybridization and immunocytochemistry in hippocampi; the expression of HCN isoforms is dynamically regulated in human as well as in experimental hippocampal epilepsy
12813043 activation of the fast channel HCN2 is dependent on the S1 segment
12194012 HCN4 activates substantially slower than HCN2 and with a half-maximum activation voltage approximately equal 10 mV less negative, both isoforms activate more positively in myocytes suggesting cell-type specificity
