Complex of R-spondin 1 with LGR4 extracellular domain

Disease

[RSPO1_HUMAN] Palmoplantar keratoderma - XX sex reversal - predisposition to squamous cell carcinoma. Keratoderma, palmoplantar, with squamous cell carcinoma of skin and sex reversal (PKKSCC) [MIM:610644]: A recessive syndrome characterized by XX (female to male) SRY-independent sex reversal, palmoplantar hyperkeratosis and predisposition to squamous cell carcinoma of the skin. Note=The disease is caused by mutations affecting the gene represented in this entry.

Function

[LGR4_HUMAN] Orphan receptor. [RSPO1_HUMAN] Activator of the beta-catenin signaling cascade, leading to TCF-dependent gene activation. Acts both in the canonical Wnt/beta-catenin-dependent pathway and in non-canonical Wnt signaling pathway, probably by acting as an inhibitor of ZNRF3, an important regulator of the Wnt signaling pathway. Acts as a ligand for frizzled FZD8 and LRP6. May negatively regulate the TGF-beta pathway. Has a essential roles in ovary determination.^{[1] [2]}
