serpin family J, Ixodes ricinus serpin-2 (IRS-2); The serpin family J clade contains serpins from the Chelicerates. This model includes serpins from the Japanese horseshoe crab, mites, ticks, and spiders. The Limulus intracellular coagulation inhibitor, designated LICI, was isolated from hemocytes of the Japanese horseshoe crab. It blocks the amidolytic activities of Limulus lipopolysaccharide-sensitive serine protease, factor C and also inhibits human alpha-thrombin, rat salivary kallikrein, bovine plasmin, and trypsin but not Limulus clotting enzyme, Limulus factor B, bovine factor Xa, human factor XIa, human tissue plasminogen activator, human urokinase, chymotrypsin, elastase, and papain. Glycosaminoglycans such as heparin and heparan sulfate had no effect on the inhibitory activity. The castor bean tick, Ixodes ricinus serpin-2 (IRS-2) whose structure has been solved, unlike that of the LICI, is found in the saliva of the tick and primarily targets 2 proinflammatory serine proteases: cathepsin G and mast cell chymase, and in higher molar excess, thrombin. It also blocks cathepsin G- and thrombin-induced platelet aggregation. Thus it has a dual role and can interfere with both inflammation and wound healing during tick feeding.

serpin miropin and similar proteins; Miropin, the serpin from Tannerella forsythia, is thought to contribute to the virulence of periodontal pathogens by inhibiting neutrophil serine proteases. Miropin broadly inhibits serine endopeptidases (SEPs) including trypsin, neutrophil elastase, pancreatic elastase, subtilisin, and cathepsin G and cysteine endopeptidases (CEPs) including papain, calpain-like peptidase Tpr, and gingipain K through various reactive-site bonds. This is achieved by offering several target bonds of the RCL for cleavage within a bait region, instead of a single RSB as found in canonical serpins. In addition, promiscuous inhibition is facilitated by the capacity to insert strands deviating from the canonical length into the central sheet A, while keeping the prey peptidase bound and inactivated. The structural adaptation of miropin to provide a relaxed inhibitory specificity, which allows for formation of inhibitory complexes using different sites, is unique among serpins.

serpin family B member 5, mammary serine proteinase inhibitor; Mammary serine proteinase inhibitor (maspin, also known as proteinase inhibitor 5/PI5), a member of the serpin superfamily, is related to the ov-serpins, with a multitude of effects on cells and tissues at an assortment of developmental stages. Maspin has tumor suppressing activity against breast and prostate cancer. All true inhibitory serpins rely on an exposed reactive center loop (RCL) to inhibit their target proteinase, in which the proteinase cleaves the RCL and becomes incorporated into a serpin-proteinase complex. Maspin differs from other serpins in that its RCL is necessary for activity, but it is not cleaved or rearranged. The ovalbumin family of serpins (ov-serpins) is a family of closely related proteins, whose members can be secreted (ovalbumin), cytosolic (leukocyte elastase inhibitor, LEI), or targeted to both compartments (plasminogen activator inhibitor 2, PAI-2). It also characterized by N- and C-terminal extensions, the absence of a signal peptide, and a Ser rather than an Asn residue at the penultimate position. The ov-serpins corresponds to clade B of the serpin superfamily.

serpin family B member 13, headpin; Headpin (also known as hurpin or proteinase inhibitor 13/P113) maps to chromosome 18q21.3 and is expressed in normal squamous epithelium of the oral mucosa, skin, and cervix. Inhibitory serpins are known to play an important role in tumor invasion, metastasis, tumor suppression and apoptosis. Headpin belongs to the ovalbumin family of serpins (ov-serpins), a family of closely related proteins, whose members can be secreted (ovalbumin), cytosolic (leukocyte elastase inhibitor, LEI), or targeted to both compartments (plasminogen activator inhibitor 2, PAI-2). It also characterized by N- and C-terminal extensions, the absence of a signal peptide, and a Ser rather than an Asn residue at the penultimate position. The ov-serpins corresponds to clade B of the serpin superfamily. In general, SERine Proteinase INhibitors (serpins) exhibit conformational polymorphism shifting from native to cleaved, latent, delta, or polymorphic forms. Many serpins, such as antitrypsin and antichymotrypsin, function as serine protease inhibitors which regulate blood coagulation cascades. Non-inhibitory serpins perform many diverse functions such as chaperoning proteins or transporting hormones. Serpins are of medical interest because mutants can cause blood clotting disorders, emphysema, cirrhosis, and dementia.

serpin family B member 1 (serpin B1), leukocyte elastase inhibitor (LEI); Leukocyte elastase inhibitor (LEI , also known as proteinase inhibitor 2/PI2, monocyte neutrophil elastase inhibitor/MNEI, EI, or ELANH2) is a member of the clade B serpins or ov-serpins (ovalbumin related serpins) that in humans is encoded by the SERPINB1 gene. Human SERPINB1 is a potent intracellular inhibitor for granzyme H (GzmH) which is constitutively expressed in NK cells and induces target cell death. GzmH cleaves SERPINB1 at Phe343 in the RCL to mediate suicide inhibition. Equine leukocyte elastase inhibitor (HLEI) in contrast to other serpins contains no carbohydrate and has a blocked amino terminus. HLEI is a thymosin beta4-binding protein suggesting a physiological role for cytoplasmic elastase inhibitors in the thymosin B4-regulated rearrangement of the cytoskeleton of leukocytes.

serpin family N, viral serpin-1 and serpin-2; This group of viral serpins are from the Orthopoxvirus branch (cowpox, ectromelia, vaccinia, variola, and rabbitpox) and corresponding to clade N which contains viral serpin-1 (SPI-1-like) and viral serpin-2 (SPI-2-like) serpins. The other is clade O which contains the viral serpin-3 (SPI-3-like) serpins. SPI-2, also called cytokine response modifier A (crmA), acts to inhibit inflammation and apoptosis. SPI-1, a serpin that is approximately 45% identical to SPI-2, has also been implicated in the inhibition of apoptosis, since certain cells infected with RPV SPI-1 mutants undergo apoptotic cell death. SERine Proteinase INhibitors (serpins) exhibit conformational polymorphism shifting from native to cleaved, latent, delta, or polymorphic forms. Many serpins, such as antitrypsin and antichymotrypsin, function as serine protease inhibitors which regulate blood coagulation cascades. Non-inhibitory serpins perform many diverse functions such as chaperoning proteins or transporting hormones. Serpins are of medical interest because mutants have been associated with blood clotting disorders, emphysema, cirrhosis, and dementia.

serpin family A member 7, thyroxine-binding globulin; Thyroxine-binding globulin (TBG, also called T4-binding globulin) is a globulin that binds thyroid hormones in circulation. It is one of three transport proteins (along with transthyretin and serum albumin) responsible for carrying the thyroid hormones thyroxine (T4) and triiodothyronine (T3) in the bloodstream. TBG is synthesized primarily in the liver and is a serpin with no inhibitory function like many other members of this class of proteins. There are two forms of inherited thyroxine-binding globulin deficiency: the complete form (TBG-CD), which results in a total loss of thyroxine-binding globulin, and the partial form (TBG-PD), which reduces the amount of this protein or alters its structure. Neither of these conditions causes any problems with thyroid function, but it can be mistaken for more serious thyroid disorders, such as hypothyroidism. This family belongs to the clade A of the serpin superfamily, which includes the classical serine proteinase inhibitors, alpha-1-antitrypsin and alpha-1-antichymotrypsin, protein C inhibitor, kallistatin, and non-inhibitory serpins, like corticosteroid and thyroxin binding globulins.
