Product Details

Kv4.3 K+ channel
Kv4.3 K+ channel (Potassium voltage-gated channel subfamily D member 3 ) is a member of the mammalian Shal-related family and the potassium voltage gated channel subunit family. Kv4 subunit family includes four Kv4 α subunits (Kv4.1, Kv4.2 and Kv4.3). However only Kv4.2 and Kv4.3 are predominantely epressed in the brain (Alfaro-Ruiz et al., 2005). KV4.3 subunit is encoded by gene KCND3 in human. 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).
