Summary

This gene encodes a secreted activator protein with two cysteine-rich, furin-like domains and one thrombospondin type 1 domain. The encoded protein is a ligand for leucine-rich repeat-containing G-protein coupled receptors (LGR proteins) and positively regulates the Wnt signaling pathway. In mice, the protein induces the rapid onset of crypt cell proliferation and increases intestinal epithelial healing, providing a protective effect against chemotherapy-induced adverse effects. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2014]

Forensic Context

A study in mice demonstrated that RSPO1, a protein mediating epicardial cell-endothelial cell interaction, promotes the angiogenic capacity of endothelial cells during regeneration of post-infarction neonatal hearts [Bian et al. DOI:10.3892/mmr.2025.13680].
