Summary: Predicted to enable G protein-coupled receptor binding activity and heparin binding activity. Acts upstream of or within angiogenesis; hematopoietic stem cell differentiation; and vascular endothelial growth factor receptor signaling pathway. Located in Golgi apparatus and cytosol. Is expressed in several structures, including nervous system; regenerating fin; reproductive system; steroid hormone secreting cell; and tail bud. Orthologous to human RSPO1 (R-spondin 1).

Rspo1 is required for hematopoietic stem cell specification through control of parallel signaling pathways controlling HSC specification: Wnt16/DeltaC/DeltaD and Vegfa/Tgfbeta1

hypothesized that misexpression of R-Spondin1 is necessary for AHR activation to block regeneration (R-Spondin1)

Rspo1-Wnt-VegfC-Vegfr3 signaling plays a crucial role as an endothelial-autonomous permissive cue for developmental angiogenesis.
Title: Rspo1/Wnt signaling promotes angiogenesis via Vegfc/Vegfr3.
These preliminary findings suggest some aspects of RSPO1 like differential expression linked to sex determination may be conserved in fish while other aspects like subcellular localization differ from the mammalian RSPO1.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
