Hyperpolarization-activated cation currents (Ih) appear in the heart and the brain and have a crucial role in controlling electrical pacemaker activity, contributing to biological processes such as heartbeat, sleep-wake cycle and synaptic plasticity.1,2
The Ih currents are generated by the hyperpolarization-activated cyclic nucleotide-gated channel family (HCN), which is comprised of four homologous members, HCN1-4.
Each HCN subunit consists of six transmembrane domains (TM), a pore region between TM5-TM6 and a binding domain for cyclic nucleotides (CNBD) in the cytoplasmic C-terminus.2 The HCN subunits can form functional homomers and can also co-assemble into functional heteromers.2
The channels are closely related to each other and share a homology of about 60%. However, their similarity decreases in the cytoplasmic N- and C-termini. The channels HCN1-4 mainly differ from each other in their speed of activation and the extent to which they are modulated by cAMP. HCN1, weakly affected by cAMP, is the fastest channel, followed by HCN2, HCN3 and HCN4.
HCN1 is extensively expressed in the brain, in specific areas like the neocortex, hippocampus, cerebellum and superior colliculus.2,3
Species reactivity key:
Alomone Labs is pleased to offer a highly specific antibody directed against an epitope of the rat HCN1 channel. Guinea pig Anti-HCN1 Antibody (#AGP-203) raised in guinea pig can be used in western blot and immunohistochemistry applications. It has been designed to recognize HCN1 from human, rat and mouse samples. The antigen used to immunize guinea pigs is the same as Anti-HCN1 Antibody (#APC-056) raised in rabbit. Our line of guinea pig antibodies enables more flexibility with our products such as immuno-colocalization studies, immunoprecipitation, etc.
