Kv1.3 - Shaker Related Potassium Channel Member 3

KV1.3 belongs to the delayed rectifier class, members of which allow nerve cells to efficiently repolarize following an action potential. KV1.3 is expressed in T and B lymphocytes and plays an essential role in T cell proliferation and activation. Blockade of KV1.3 channels in effector-memory T cells suppresses calcium signaling, cytokine production (interferon-gamma, interleukin 2) and cell proliferation. KV1.3 is an important target for drug development for autoimmune diseases as Multiple Sclerosis, type-1 diabetes mellitus and rheumatoid arthritis.

Family: Potassium channels

Subgroups: Shaker (KV1.1–KV1.8), Shab (KV2.1-KV2.2), Shaw (KV3.1–KV3.4), Shal (KV4.1–KV4.3), KQT like (KV7.1–KV7.5), Eag related (KV10.1-KV10.2), Erg related (KV11.1–KV11.3), Elk related (KV12.1)

Topology: Contains six transmembrane domains (S1–S6), four single subunits form a pore, homotetramers and heterotetramers are possible
