这个基因编码一个R-反应蛋白家族的成员。这些蛋白是富含亮氨酸重复序列的分泌配体，含有g蛋白偶联受体，通过抑制泛素e3连接酶增强wnt信号传导。在多种人类癌症中，包括这个基因座在内的染色体易位导致了基因融合的形成。选择性剪接导致多个转录变体。[由RefSeq提供，2015年12月]
This gene encodes a member of the R-spondin family of proteins. These proteins are secreted ligands of leucine-rich repeat containing G protein-coupled receptors that enhance Wnt signaling through the inhibition of ubiquitin E3 ligases. A chromosomal translocation including this locus that results in the formation of a gene fusion has been identified in multiple human cancers. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2015]
