Research Abstract |
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.
