HCN3 Antibody – Rabbit Polyclonal

Biological rhythms (beating of the heart, circadian sleep cycles, respiration, and the release of hormones) are necessary to sustain life. Heart beating is the most reliable and rhythmic biological phenomenon. Cardiac pacemaking is produced by the slow diastolic depolarization phase of the action potential. The hyperpolarization-activated cation current (termed If, Ih, or Iq) plays a key role in the in the initiation and modulation of cardiac and neuronal pacemaker depolarization. The generation of cardiac pacemaker potentials relies on a complex interplay between at least four different types of cation channels: T- and L-type Ca2+ channels, K+ channels, and a cation channel termed If (synonymous names are Ih and Iq). The If channel has been designated as "pacemaker" channel because it reveals unique features that are believed to be a prerequisite for pacemaker activity. Recently, the hyperpolarization-activated cyclic nucleotide-gated families of ion channel proteins (HCN1-4) have been identified as the "pacemaker" channel. The amino acid sequences of HCNs predict a structure similar to that of voltage-gated (Kv) channels and cyclic nucleotide-gated (CNG) channels. HCNs proteins (HCN1-4) are characterized by six transmembrane domains (S1-S6), including a including a positively charged voltage-sensing S4 segment and an ion-conducting pore between S5 and S6. In the C terminus the HCNs carry a cyclic nucleotide-binding domain (CNBD), a motif found in several cyclic nucleotide-binding proteins. The core region of HCNs channels (S1 to the C terminus of the CNBD) is highly conserved, whereas the cytoplasmic N and C-termini, vary considerably in their length and share only weak sequence homology. The functional HCN, like other members of the superfamily of voltage-gated cation channels, channels probably assemble into tetrameric complexes. HCN3 or HAC3 (rat 780aa, mouse 779aa, human 703aa) has been detected in brain but its expression was much less than other HCNs. Its expression was also detected in liver, lung, and kidney of mouse by some researchers but not by others.

Small volumes of anti-HCN3 antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
