背景介绍
Potassium channels represent the most complex class of
voltage-gated ion channels from both functional and structural
standpoints. Their diverse functions include regulating
neurotransmitter release, heart rate, insulin secretion, neuronal
excitability, epithelial electrolyte transport, smooth muscle
contraction, and cell volume. Four sequence-related potassium
channel genes - shaker, shaw, shab, and shal - have been identified
in Drosophila, and each has been shown to have human homolog(s).
This gene encodes a member of the potassium channel, voltage-gated,
shaker-related subfamily. This member contains six
membrane-spanning domains with a shaker-type repeat in the fourth
segment. It belongs to the delayed rectifier class, members of
which allow nerve cells to efficiently repolarize following an
action potential. The coding region of this gene is intronless, and
the gene is clustered with genes KCNA3 and KCNA10 on chromosome 1.
组织表达
Detected in brain cortex (PubMed:16473933). Detected in peroneal nerve in the juxtaparanodal regions of the node of Ranvier; expression is decreased in patients with diabetes mellitus that suffer from axonal neuropathy (PubMed:22649228). Detected in paranodal and juxtanodal zones in myelinated spinal cord (at protein level) (PubMed:11086297).
