This gene encodes a member of the R-spondin family of proteins that share a common domain organization consisting of a signal peptide, cysteine-rich/furin-like domain, thrombospondin domain and a C-terminal basic region. The encoded protein may be involved in activation of Wnt/beta-catenin signaling pathways. Mutations in this gene are associated with anonychia congenital. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Sep 2009]
GeneCards Summary for RSPO4 Gene
RSPO4 (R-Spondin 4) is a Protein Coding gene. Diseases associated with RSPO4 include Anonychia Congenita and Nail Disease. Among its related pathways are Wnt Signaling Pathways: beta-Catenin-independent Wnt/PCP Signaling Pathways and Signaling by GPCR. GO annotations related to this gene include heparin binding and G-protein coupled receptor binding. An important paralog of this gene is RSPO2.
UniProtKB/Swiss-Prot for RSPO4 Gene
Activator of the canonical Wnt signaling pathway by acting as a ligand for LGR4-6 receptors. Upon binding to LGR4-6 (LGR4, LGR5 or LGR6), LGR4-6 associate with phosphorylated LRP6 and frizzled receptors that are activated by extracellular Wnt receptors, triggering the canonical Wnt signaling pathway to increase expression of target genes. Also regulates the canonical Wnt/beta-catenin-dependent pathway and non-canonical Wnt signaling by acting as an inhibitor of ZNRF3, an important regulator of the Wnt signaling pathway.
