Recombinant human KCNF1 protein is derived from the potassium voltage-gated channel subfamily F member 1 (KCNF1), a key component of voltage-gated potassium (Kv) channels. These channels regulate electrical signaling in excitable cells, including neurons and muscle cells, by controlling potassium ion flow during action potentials. KCNF1. also known as Kv5.1. belongs to the "silent" Kv subfamily, as it does not form functional homotetramers but instead modulates the activity of other Kv α-subunits (e.g., Kv2) by forming heteromeric complexes. This interaction alters channel kinetics, voltage dependence, and trafficking, influencing cellular excitability.
Recombinant KCNF1 is produced using expression systems like HEK293 or E. coli, enabling studies on its structure-function relationships, regulatory roles, and pathological mechanisms. Mutations in KCNF1 have been linked to neurological disorders, including epilepsy and developmental delays, making this protein a focus for understanding channelopathies. Its recombinant form facilitates drug discovery, electrophysiological assays, and antibody development. Research also explores its role in cancer, as potassium channels influence cell proliferation and apoptosis. By providing a pure, scalable protein source, recombinant KCNF1 advances mechanistic insights and therapeutic targeting in diverse diseases.
