E3 ubiquitin-protein ligase ZNRF3

Gene

Znrf3

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

E3 ubiquitin-protein ligase that acts as a negative regulator of the Wnt signaling pathway by mediating the ubiquitination and subsequent degradation of Wnt receptor complex components Frizzled and LRP6. Acts on both canonical and non-canonical Wnt signaling pathway. Acts as a tumor suppressor in the intestinal stem cell zone by inhibiting the Wnt signaling pathway, thereby resticting the size of the intestinal stem cell zone.2 Publications

Enzyme regulationi

Negatively regulated by R-spondin proteins such as RSPO1: interaction with RSPO1 induces the indirect association between ZNRF3 and LGR4, promoting membrane clearance of ZNRF3.By similarity

Pathwayi: protein ubiquitination

This protein is involved in the pathway protein ubiquitination, which is part of Protein modification.
View all proteins of this organism that are known to be involved in the pathway protein ubiquitination and in Protein modification.

Disruption phenotypei

Embryos die around birth due to activation of Wnt signaling pathway. Embryos display a lack of lens formation due to Wnt activation. Conditional knockout mice lacking both Rnf43 and Znrf3 in intestine show a marked expansion of the proliferative compartment, resembling the effects of acute deletion of Apc.2 Publications

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.
