The protein encoded by this gene is a member of the keratin family. The keratins are intermediate filament proteins responsible for the structural integrity of epithelial cells and are subdivided into cytokeratins and hair keratins. The type I cytokeratins consist of acidic proteins which are arranged in pairs of heterotypic keratin chains. The type I cytokeratin genes are clustered in a region of chromosome 17q12-q21. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]
Function:
Receptor for Dickkopf protein. Cooperates with Dickkopf to block Wnt/beta-catenin signaling. Forms a ternary complex with Dkk1 and LRP6 and induces rapid endocytosis and removal of the Wnt receptor LRP6 from the plasma membrane (By similarity).
Subunit:
Interacts with ERLEC1 (By similarity).
Subcellular Location:
Membrane; Single-pass type I membrane protein (Potential).
Similarity:
Contains 1 CUB domain.
Contains 1 kringle domain.
Contains 1 WSC domain.
