SLC34A2（solute carrier family 34 member 2），癌症关联基因，基因ID：10568，该基因编码的蛋白质是一种ph敏感的钠依赖性磷酸转运体。在较低的ph值下，磷酸盐摄取增加。该基因缺陷是肺泡微结石的一个原因。已经发现了三个编码两种不同亚型的转录变体。[由RefSeq提供，2010年5月]The protein encoded by this gene is a pH-sensitive sodium-dependent phosphate transporter. Phosphate uptake is increased at lower pH. Defects in this gene are a cause of pulmonary alveolar microlithiasis. Three transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq， May 2010]。
