The first cupredoxin domain of Ceruloplasmin; Ceruloplasmin is a multicopper oxidase essential for normal iron homeostasis and copper transport in blood. It also functions in amine oxidation and as an antioxidant preventing free radicals in serum. The protein has 6 cupredoxin domains with six copper centers; three mononuclear sites in domain 2, 4 and 6 and three in the form of trinuclear clusters at the interface of domains 1 and 6. Ceruloplasmin exhibits internal sequence homology that appears to have evolved from the triplication of a sequence unit composed of two tandem cupredoxin domains. This model represents the first cupredoxin domain of ceruloplasmin.

Cupredoxin superfamily; Cupredoxins contain type I copper centers and are involved in inter-molecular electron transfer reactions. Cupredoxins are blue copper proteins, having an intense blue color due to the presence of a mononuclear type 1 (T1) copper site. Structurally, the cupredoxin-like fold consists of a beta-sandwich with 7 strands in 2 beta-sheets, which is arranged in a Greek-key beta-barrel. Some of these proteins have lost the ability to bind copper. The majority of family members contain multiple cupredoxin domain repeats: ceruloplasmin and the coagulation factors V/VIII have six repeats; laccase, ascorbate oxidase, spore coat protein A, and multicopper oxidase CueO contain three repeats; and nitrite reductase has two repeats. Others are mono-domain cupredoxins, such as plastocyanin, pseudoazurin, plantacyanin, azurin, rusticyanin, stellacyanin, quinol oxidase, and the periplasmic domain of cytochrome c oxidase subunit II.

Cupredoxin domains 2, 4, and 6 of ceruloplasmin and similar proteins; This family includes the second, fourth and sixth cupredoxin domains of ceruloplasmin and similar proteins, including the second, fourth, and sixth cupredoxin domains of unprocessed coagulation factors V and VIII. Ceruloplasmin (ferroxidase) is a multicopper oxidase essential for normal iron homeostasis. Ceruloplasmin also functions in copper transport, amine oxidase and as an antioxidant preventing free radicals in serum. The protein has 6 cupredoxin domains and exhibits internal sequence homology that appears to have evolved from the triplication of a sequence unit composed of two tandem cupredoxin domains. Human Factor VIII facilitates blood clotting by acting as a cofactor for factor IXa Factor VIII and IXa forms a complex in the presence of Ca+2 and phospholipids that converts factor X to the activated form Xa.

The first cupredoxin domain of coagulation factor VIII and similar proteins; Factor V is an essential coagulation protein with both pro- and anti-coagulant functions. Aberrant expression of human factor V can lead to bleeding or thromboembolic disease, which may be life-threatening. Bovine factor Va serves as the cofactor in the prothrombinase complex that results in a 300,000-fold increase in the rate of thrombin generation. Factor V is synthesized as a single polypeptide with six cupredoxin domains and a domain structure of 1-2-3-4-B-5-6-C1-C2, where 1-6 are cupredoxin domains, B is a domain with no known structural homologs and is dispensible for coagulant activity, and C are domains distantly related to discoidin protein-fold family members. Factor V has little activity prior to proteolytic cleavage by thrombin or FXa upon secretion. The resulting Factor Va is a heterodimer consisting of a heavy chain (1-2-3-4) and a light chain (5-6-C1-C2). This model represents the cupredoxin domain 1 of unprocessed Factor V or the heavy chain of Factor Va, and similar proteins including pseutarin C non-catalytic subunit. Pseutarin C is a prothrombin activator from Pseudonaja textilis venom.

The first cupredoxin domain of coagulation factor VIII and similar proteins; Factor VIII functions in the factor X-activating complex of the intrinsic coagulation pathway. It facilitates blood clotting by acting as a cofactor for factor IXa. In the presence of Ca2+ and phospholipids, Factor VIII and IXa form a complex that converts factor X to the activated form Xa. A variety of mutations in the Factor VIII gene can cause hemophilia A, which typically requires replacement therapy with purified protein. Factor VIII is synthesized as a single polypeptide with six cupredoxin domains and a domain structure of 1-2-3-4-B-5-6-C1-C2, where 1-6 are cupredoxin domains, B is a domain with no known structural homologs and is dispensible for coagulant activity, and C are domains distantly related to discoidin protein-fold family members. Factor VIII is initially processed through proteolysis to generate a heterodimer consisting of a heavy chain (1-2-3-4) and a light chain (5-6-C1-C2), which circulates in a tight complex with von Willebrand factor (VWF). Further processing of the heavy chain produces activated factor VIIIa, a heterotrimer composed of polypeptides (1-2), (3-4), and the light chain. This model represents the cupredoxin domain 1 of unprocessed Factor VIII or the heavy chain of circulating Factor VIII, and similar proteins.
