Functioni

Required for normal renal development and establishment of left-right axis. Probably acts as a molecular switch between different Wnt signaling pathways. Inhibits the canonical Wnt pathway by targeting cytoplasmic disheveled (DVL1) for degradation by the ubiquitin-proteasome. This suggests that it is required in renal development to oppose the repression of terminal differentiation of tubular epithelial cells by Wnt signaling (By similarity). Involved in the organization of apical junctions in kidney cells together with NPHP1, NPHP4 and RPGRIP1L/NPHP8. Does not seem to be strictly required for ciliogenesis.By similarity3 Publications

Expressioni

Tissue specificityi

Strongly expressed in the primary cilia of renal cells, especially in the varicosities, swellings observed in the cilia. Localizes in the node monocilia and in other 9+0 monocilia, including those of kidney epithelial cells and the pituitary gland, but it does not localize to 9+2 cilia (at protein level). In adult, it is expressed at high level in liver and kidney. Weakly or not expressed in other tissues.2 Publications

Developmental stagei

Expressed from E7. Expressed in presomite-stage embryos, before asymmetrical expression of Nodal and Lefty.1 Publication

Interactioni

Subunit structurei

Interacts with microtubules. Interacts with NPHP1. Interacts with DVL1, PRICKLE (PRICKLE1 or PRICKLE2) and Strabismus (VANGL1 or VANGL2) (By similarity). Binds calmodulin via its IQ domains. Interacts with APC2. Interacts with alpha-, beta-, and gamma-catenin. Interacts with N-cadherin (CDH2). Interacts with NPHP3 (By similarity). Interacts with IQCB1; the interaction likely requires additional interactors (By similarity). Component of a complex containing at least ANKS6, INVS, NEK8 and NPHP3. ANKS6 may organize complex assembly by linking INVS and NPHP3 to NEK8 and INVS may target the complex to the proximal ciliary axoneme (By similarity).By similarity

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
