R-spondin-1 is also known as Roof plate-specific Spondin 1 (RSPO1) and cysteinerich and single thrombospondin domain containing protein 3 (Cristin 3), which is a secreted protein which belongs to the R-Spondin family and encodes a secreted activator protein with two cystein-rich, furin-like domains and one thrombospondin type 1 domain.
All Rspondins regulate Wnt/β-catenin signaling, but have distinct expression patterns.
Like other R-Spondins, R-Spondin-1 contains two adjacent cysteinerich furinlike domains (aa 34-135) with one potential N-glycosylation site, followed by a thrombospondin (TSP1) motif (aa 147-207) and a region rich in basic residues (aa 211-263).
Only the furinlike domains are needed for β-catenin stabilization.
A putative nuclear localization signal at the C-terminus may allow some expression in the nucleus.
特徴
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 14.6 kDa.
The protein migrates as 20-22 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
