<p>This entry represents complement control protein (CCP) modules, which are also known as sushi domains or short consensus repeats (SCR). The CCP module is a disulphide-rich domain with an all-beta fold. These domains are found in a wide variety of complement and adhesion proteins, such as complement receptors Cr1 and Cr2 [<cite idref="PUB00029954"/>], complement C1R and C1S proteases [<cite idref="PUB00018395"/>], and complement decay-accelerating factor CD55 [<cite idref="PUB00021726"/>], as well as in mannan-binding lectin serine protease 2 (MASP-2) [<cite idref="PUB00030108"/>], GABA-B receptor 1 [<cite idref="PUB00037637"/>], beta2-glycoprotein [<cite idref="PUB00030387"/>], membrane cofactor protein CD46 [<cite idref="PUB00021342"/>], and as the 15th and 16th modules of Factor H [<cite idref="PUB00036876"/>]. </p> Complement control module
