Summary
Predicted to enable several functions, including calcium ion binding activity; identical protein binding activity; and serine-type endopeptidase activity. Predicted to be involved in zymogen activation. Predicted to be located in extracellular region. Predicted to be active in extracellular space. Human ortholog(s) of this gene implicated in Ehlers-Danlos syndrome periodontal type 1. Orthologous to human C1R (complement C1r). [provided by Alliance of Genome Resources, Nov 2024]

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.
