Voltage-gated potassium channel that mediates transmembrane potassium transport in excitable membranes. Forms tetrameric potassium-selective channels through which potassium ions pass in accordance with their electrochemical gradient. The channel alternates between opened and closed conformations in response to the voltage difference across the membrane (PubMed:19912772, PubMed:8495559). Can form functional homotetrameric channels and heterotetrameric channels that contain variable proportions of KCNA1, KCNA2, KCNA4, KCNA5, and possibly other family members as well; channel properties depend on the type of alpha subunits that are part of the channel (PubMed:8495559). Channel properties are modulated by cytoplasmic beta subunits that regulate the subcellular location of the alpha subunits and promote rapid inactivation. In vivo, membranes probably contain a mixture of heteromeric potassium channel complexes, making it difficult to assign currents observed in intact tissues to any particular potassium channel family member. Homotetrameric KCNA4 forms a potassium channel that opens in response to membrane depolarization, followed by rapid spontaneous channel closure (PubMed:19912772, PubMed:8495559). Likewise, a heterotetrameric channel formed by KCNA1 and KCNA4 shows rapid inactivation (PubMed:17156368).

Kv1.4 also known as RK3 functions as a voltage-gated potassium channel. It allows for potassium ions to move across the cell membrane in response to changes in membrane potential. This channel has a molecular mass around 75 kDa. Kv1.4 is mainly expressed in cardiac and neuronal tissues where it plays an important role in action potential repolarization. Its expression ensures proper electrical signaling in these tissues.
The Kv1.4 channel contributes to the regulation of action potentials in both the heart and nervous system. It is part of a larger complex of potassium channels that work together to fine-tune neuronal excitability and muscle contraction. The function of Kv1.4 is essential for maintaining the balance of excitation and inhibition in cells impacting how electrical signals are transmitted.
Kv1.4 has a significant role in the cardiac action potential pathway and the neural signaling pathway. In the cardiac pathway it interacts with other potassium channels like Kv1.2 and Kv1.1 to ensure the timely repolarization of the cardiac action potential. In neural tissues Kv1.4 affects neurotransmitter release and neuronal firing rates interacting with proteins such as synaptotagmin in the synaptic vesicle fusion process.
Kv1.4 mutations and dysregulation are connected to cardiac arrhythmias and epilepsy. Altered Kv1.4 function can disrupt the cardiac rhythm leading to arrhythmogenic conditions. In epilepsy abnormal Kv1.4 activity may lead to imbalanced neuronal excitability which can contribute to seizure disorders. Kv1.4 interacts with other proteins like Nav1.1 in these disease states to exacerbate or mitigate symptoms.
