Background: R-Spondin 3

RSPO-3 (R-spondin 3; also Cristin-1), is a 256 aa secreted R-Spondin family member which binds LRP-6 and Fzd8 and regulates beta -catenin signaling. R-Spondins contain two adjacent cysteine-rich furin-like domains at their amino-termini, followed by a thrombospondin (TSP-1) motif and a variable length basic C-terminal region. Two RSPO-3 splice isoforms that differ in their C-termini have been reported. Mouse RSPO-3 shares 93% and 97% aa identity with human and rat RSPO-3, respectively, over the sequence used as an immunogen.
