Summary
Enables heparin binding activity. Acts upstream of or within several processes, including embryonic limb morphogenesis; negative regulation of odontogenesis of dentin-containing tooth; and respiratory system development. Located in cell surface and extracellular region. Is expressed in several structures, including brain; jaw; limb bud; pelvic urethra; and sensory organ. Human ortholog(s) of this gene implicated in tetraamelia syndrome 2. Orthologous to human RSPO2 (R-spondin 2). [provided by Alliance of Genome Resources, Apr 2022]
Expression
Biased expression in CNS E11.5 (RPKM 3.5), CNS E18 (RPKM 1.5) and 8 other tissues See more

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.
