Official Full Name complement component 2
Background Component C2 is a serum glycoprotein that functions as part of the classical pathway of the complement system. Activated C1 cleaves C2 into C2a and C2b. The serine proteinase C2a then combines with complement factor 4b to create the C3 or C5 convertase. Deficiency of C2 has been reported to associated with certain autoimmune diseases and SNPs in this gene have been associated with altered susceptibility to age-related macular degeneration. This gene localizes within the class III region of the MHC on the short arm of chromosome 6. Alternative splicing results in multiple transcript variants encoding distinct isoforms. Additional transcript variants have been described in publications but their full-length sequence has not been determined.[provided by RefSeq, Mar 2009]

    C2 has several biochemical functions, for example, metal ion binding, serine-type endopeptidase activity. Some of the functions are cooperated with other proteins, some of the functions could acted by C2 itself. We selected most functions C2 had, and list some proteins which have the same functions with C2. You can find most of the proteins on our site.

    C2 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 C2 here. Most of them are supplied by our site. Hope this information will be useful for your research of C2.
