关于 SLC17A4

功能概要

通过调节磷酸盐的摄入量、肠道吸收、骨沉积和吸收以及肾脏排泄来维持磷酸盐稳态。控制肾脏排泄磷酸盐的中心分子是钠/磷酸盐协同转运蛋白 NPT1 (SLC17A1；MIM 182308) ，它位于肾近端小管。 NPT1 利用钠的跨膜电化学势梯度将磷酸盐转运穿过细胞膜。 SLC17A4 是肠粘膜中类似的钠/磷酸盐协同转运蛋白，在肠道吸收磷酸盐方面起着重要作用 (Shibui 等人总结，1999 [PubMed 10319585]) 。[OMIM 提供，2011 年 2 月]

Phosphate homeostasis is maintained by regulating intake, intestinal absorption, bone deposition and resorption, and renal excretion of phosphate. The central molecule in the control of phosphate excretion from the kidney is the sodium/phosphate cotransporter NPT1 (SLC17A1; MIM 182308), which is located in the renal proximal tubule. NPT1 uses the transmembrane electrochemical potential gradient of sodium to transport phosphate across the cell membrane. SLC17A4 is a similar sodium/phosphate cotransporter in the intestinal mucosa that plays an important role in the absorption of phosphate from the intestine (summary by Shibui et al., 1999 [PubMed 10319585]).[supplied by OMIM, Feb 2011]
