Tiki homology domain antagonizes Wnt function via cleavage of amino-terminal residues; Tiki is a membrane-associated metalloprotease that inhibits Wnt via the cleavage of its amino terminus, diminishing Wnt's binding to receptors. Wnt is essential in animal development and homeostasis. In xenopus, tiki is critical in head development. In human cells, TIKI inhibits Wnt-signaling, which is important in embryogenesis, homeostasis, and regeneration. Deregulation of WNT contributes to birth defects, cancer and various diseases. TIKI homology domains are part of the TraB family and are related to the Erythromycin esterase, GumN plant pathogens, RtxA toxins, and Campylobacter Jejuni heme-binding, Chan-like proteins. TraB/PrgY are identified in gut bacterium Enterococcus faecalis, but its function has not been well characterized. Plasmid-borne, TraB has been implicated in the regulation of pheromone sensitivity and specificity. Based on homology to TIKI activity, it has been proposed that TraB acts as a metalloprotease in the inactivation of mating pheromone. The TIKI/TraB family has 2 conserved GxxH motifs and conserved glutamate and arginine residues that may be catalytic.

TraB/PrgY/gumN family; This entry includes Tiki1/2 from humans, TraB/PrgY from the gut flora Enterococcusfaecalis and gumN from the plant pathogen Xanthomonas. Tiki1 is homologous to TraB/PrgY. They have a pair of widely spaced GX2H motifs and a conserved glutamate. From the structural study, this group of proteins have been identified as an ancient metalloprotease clan with a common protein architecture (cobbled from the folds of the EreA/ChaN/PMT group) that mediates proteolytic activities. Tiki1 is a membrane-associated protease that inhibits Wnt via the cleavage of its amino terminus, diminishing Wnt's binding to receptors. TraB/PrgY is an inhibitor peptide that may act as a protease to inactivate the mating pheromone.

Click on the triangle to view details about the feature, including a multiple sequence alignment
of your query sequence and the protein sequences used to curate the domain model,
where hash marks (#) above the aligned sequences show the location of the conserved feature residues.
The thumbnail image, if present, provides an approximate view of the feature's location in 3 dimensions.

This image shows a graphical summary of conserved domains identified on the query sequence.
The Show Concise/Full Display button at the top of the page can be used to select the desired level of detail: only top scoring hits
(labeled illustration) or all hits

Domains are color coded according to superfamilies
to which they have been assigned. Hits with scores that pass a domain-specific threshold
(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.
