Korean Central News Agency
The Korean Central News Agency (KCNA) is the state news agency of North Korea that was established on December 5, 1946. The agency portrays the views of the Workers' Party of Korea and the North Korean government for foreign consumption. KCNA is headquartered in the capital city of Pyongyang. In South Korea, access to both KCNA websites: www.kcna.kp and www.kcna.co.jp, is blocked by the South Korean government.
Organization
As the sole news agency of North Korea, KCNA daily reports news for all the North Korean news organizations including newspapers, radio and television broadcasts via Korean Central Television and the Korean Central Broadcasting System within the country. In December 1996, KCNA began publishing its news articles on the Internet with its web server located in Japan. Since October 2010, stories have been published on a new site, controlled from Pyongyang, and output has been significantly increased to include world stories with no specific link to North Korea as well as news from countries that have strong DPRK ties.
KCNA5
Potassium voltage-gated channel, shaker-related subfamily, member 5, also known as KCNA5 or Kv1.5, is a protein that in humans is encoded by the KCNA5 gene.
Function
Potassium channels represent the most complex class of voltage-gated ion channels from both functional and structural standpoints. KCNA5 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, the function of which could restore the resting membrane potential of beta cells after depolarization, thereby contributing to the regulation of insulin secretion. This gene is intronless, and the gene is clustered with genes KCNA1 and KCNA6 on chromosome 12. Mutations in this gene have been related to both atrial fibrillation and sudden cardiac death. KCNA5 are also key players in pulmonary vascular function, where they play a role in setting the resting membrane potential and its involvement during hypoxic pulmonary vasoconstriction.
KCNA4
Potassium voltage-gated channel subfamily A member 4 also known as Kv1.4 is a protein that in humans is encoded by the KCNA4 gene. It contributes to the cardiac transient outward potassium current (Ito1), the main contributing current to the repolarizing phase 1 of the cardiac action potential.
Description
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 A-type potassium current class, the members of which may be important in the regulation of the fast repolarizing phase of action potentials in heart and thus may influence the duration of cardiac action potential. The coding region of this gene is intronless, and the gene is clustered with genes KCNA3 and KCNA10 on chromosome 1 in humans.
