    C1R has several biochemical functions, for example, calcium ion binding, protein binding, serine-type endopeptidase activity. Some of the functions are cooperated with other proteins, some of the functions could acted by C1R itself. We selected most functions C1R had, and list some proteins which have the same functions with C1R. You can find most of the proteins on our site.

    C1R has direct interactions with proteins and molecules. Those interactions were detected by several methods such as yeast two hybrid, co-IP, pull-down and so on. We selected proteins and molecules interacted with C1R here. Most of them are supplied by our site. Hope this information will be useful for your research of C1R.
