C1rb - complement component 1, r subcomponent B

Predicted to enable calcium ion binding activity; identical protein binding activity; and serine-type endopeptidase activity. Predicted to be involved in zymogen activation. Predicted to act upstream of or within complement activation, classical pathway and innate immune response. Predicted to be active in blood microparticle. 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, Apr 2022]
