项目摘要
It has been reported that two splicing variants of URATv1 are exist. One is the short isoform (URATv1-S) that composed with 512 amino acids and the other one is the long isoform (URATv1-L) that composed with 540 amino acids. URATv1-S was expressed in apical side of renal distal tubules. On the other hand, URATv1-L was expressed in basolateral side of renal proximal tubules.GFP fused URATv1s were expressed in MDCK cells and intracellular localization was observed to analyze trafficking mechanism in vitro. It seems that N-terminal of URATv1-L includes sorting signal to basolateral membrane.
URATv 1存在两种剪接变异体。URATv 1-S是由512个氨基酸组成的短亚型,URATv 1-L是由540个氨基酸组成的长亚型。URATv 1-S表达于肾远端小管顶侧。另一方面,URATv 1-L在肾近端小管的基底外侧表达,在MDCK细胞中表达GFP融合的URATv 1,并观察其细胞内定位,分析URATv 1在体外的运输机制。URATv 1-L的N-末端可能包含了对基底外侧膜的分选信号。
