NBC1/SLC4A4 is an eletrogenic sodium bicarbonate cotransporter. It mediates the coupled movement of Na+ and HCO3- ions across the basolateral membrane of cells. NBC1 regulates secretion and absorption of bicarbonate and modulates intracellular pH (1-3). There are five isoforms of NBC1 produced by alternative splicing including the most studied isoforms, 1 and 2, which have different N termini. The N terminus of isoform 1 contains multiple consensus phosphorylation sites for various kinases, such as PKA, PKC, and CK II, and may play a regulatory role in the biological function of NBC1 (4). Interaction with carbonic anhydrase II, IV, and IX regulates the transporter acitivity of NBC1 (5-7). NBC1 is expressed in various tissues with the exception of isoform 2, which is mainly expressed in kidney proximal tubules (1). Isoform 1 is expressed in the pancreas and corneal endothelium, and at low levels in other tissues including heart, skeletal muscle, liver, and prostate (4). Research studies have shown that mutations in the NBC1 gene are linked to proximal renal tubular acidosis with ocular abnormalities (also known as renal tubular acidosis II).

NBC1/SLC4A4是生电的碳酸氢钠协同转运蛋白。它介导Na +和HCO3-离子跨越细胞基底膜的耦合运动。 NBC1调节碳酸氢盐分泌和吸收,并调节细胞内pH值(1-3)。NBC1共有五种选择性剪接异构体,其中研究最多的异构体1和2,它们具有不同的N端。异构体1的N末端的包含各种激酶的多重磷酸化识别位点,如PKA,PKC,CK II,并可能对NBC1的生物学功能起到调节作用(4)。与碳酸酐酶II,IV和IX互作能调节NBC1的转运活性(5-7)。除异构体2主要是在肾近端小管表达外(1),NBC1在各种组织中都有表达。亚型1主要在胰和角膜内皮细胞表达,在其他组织,包括心脏,骨骼肌,肝脏,前列腺中表达水平较低(4)。研究表明,NBC1基因的突变与近端肾小管酸中毒(也被称为肾小管性酸中毒II)相关,该病会出现眼部异常。
