功能概要

丙酮酸脱氢酶 (PDH) 复合物位于线粒体基质中,催化丙酮酸转化为乙酰辅酶 A。因此,PDH 复合物将糖酵解与克雷布斯循环联系起来。 PDH 复合物包含三个催化亚基 E1、E2 和 E3,两个调节亚基 E1 激酶和 E1 磷酸酶,以及一个非催化亚基 E3 结合蛋白 (E3BP) 。该基因编码 E3 结合蛋白亚基;也称为丙酮酸脱氢酶复合物的组分 X。这种蛋白质将 E3 二聚体连接到 PDH 复合体的 E2 核心。该基因的缺陷是丙酮酸脱氢酶缺乏症的一个原因,它会导致婴儿期和幼儿期的神经功能障碍和乳酸性酸中毒。这种蛋白质也是抗线粒体抗体的次要抗原。这些自身抗体存在于近 95% 的自身免疫性肝病原发性胆汁性肝硬化 (PBC) 患者中。在 PBC 中,活化的 T 淋巴细胞攻击并破坏胆管中的上皮细胞,该蛋白质在该处异常分布和过度表达。 PBC 最终导致肝硬化和肝功能衰竭。可变剪接导致编码不同亚型的多个转录变体。[RefSeq 提供,2009 年 10 月]

The pyruvate dehydrogenase (PDH) complex is located in the mitochondrial matrix and catalyzes the conversion of pyruvate to acetyl coenzyme A. The PDH complex thereby links glycolysis to Krebs cycle. The PDH complex contains three catalytic subunits, E1, E2, and E3, two regulatory subunits, E1 kinase and E1 Phosphatase, and a non-catalytic subunit, E3 binding protein (E3BP). This gene encodes the E3 binding protein subunit; also known as component X of the pyruvate dehydrogenase complex. This protein tethers E3 dimers to the E2 core of the PDH complex. Defects in this gene are a cause of pyruvate dehydrogenase deficiency which results in neurological dysfunction and lactic acidosis in infancy and early childhood. This protein is also a minor antigen for antimitochondrial Antibodies. These autoantibodies are present in nearly 95% of patients with the autoimmune liver disease primary biliary cirrhosis (PBC). In PBC, activated T lymphocytes attack and destroy epithelial cells in the bile duct where this protein is abnormally distributed and overexpressed. PBC eventually leads to cirrhosis and liver failure. Alternative splicing results in multiple transcript variants encoding distinct isoforms.[provided by RefSeq, Oct 2009]
