Anti-Kv4.2 K+ Channel Antibody
Kv4.2 K+ channel
Kv4.2 K+ channel (Potassium voltage-gated channel subfamily D member 2 ) is a member of the mammalian Shal-related family and potassium voltage gated channel subunit family. Kv4 subunit family includes four Kv4 a subunits (Kv4.1, Kv4.2 and Kv4.3). However only Kv4.2 and Kv4.3 are predominantely expressed in the brain (Alfaro-Ruiz et al., 2019). Kv4.2 K+ is encoded by gene KCND2 in human. It helps to regulate the action potential's circadian rhythm firing in suprachiasmatic nucleus neurons. This process regulates the circadian rhythm of locomotor activity. It has been demonstrated that Kv 4.2 and Kv4.3 are often colocalized with pain-modulating molecules in rat spinal lamina II excitatory interneurons (Huang et al., 2005).
