ANTI-POTASSIUM CHANNEL KIR4.1

Monoclonal Anti-KCNJ10 antibody has been used in immunohistochemistry.

This gene encodes a member of the inward rectifier-type potassium channel family, characterized by having a greater tendency to allow potassium to flow into, rather than out of, a cell. The encoded protein may form a heterodimer with another potassium channel protein and may be responsible for the potassium buffering action of glial cells in the brain. Mutations in this gene have been associated with seizure susceptibility of common idiopathic generalized epilepsy syndromes. (provided by RefSeq)

Kir4.1/KCNJ10 (potassium voltage-gated channel subfamily J member 10) helps to regulate the basolateral K+ conductance in the DCT (distal convoluted tubule). It participates in the K+ spatial buffering process, that helps to maintain the resting membrane potential of neurons. Kir4.1 is essential for producing the endocochlear potential of intermediate cells and for retaining high K+ content of the endolymph in ear. In the eye, Kir4.1 plays a vital role in the modulation of the extracellular K+ level and in controlling the healing process of cornea epithelial cells. Mutations in KCNJ10 results in SeSAME (seizures, sensorineural deafness, ataxia, mental retardation and electrolyte imbalance).
