产品介绍 : Pregnancy Zone protein is a 1,482 amino acid secreted protein that belongs to the protease inhibitor I39 family and exists as multiple alternatively spliced isoforms. Expressed predominately in plasma and in late-pregnancy sera, Pregnancy Zone protein functions as a disulfide-linked homotetramer that is able to trap and inhibit proteinases, thus playing a role in the regulation of protein splitting and small peptide formation. The gene encoding Pregnancy Zone protein maps to human chromosome 12, which encodes over 1,100 genes and comprises approximately 4.5% of the human genome. Chromosome 12 is associated with a variety of diseases and afflictions, including hypochondrogenesis, achondrogenesis, Kniest dysplasia, Noonan syndrome and Trisomy 12p, which causes facial developmental defects and seizure disorders.
Function:
Is able to inhibit all four classes of proteinases by a unique 'trapping' mechanism. This protein has a peptide stretch, called the 'bait region' which contains specific cleavage sites for different proteinases. When a proteinase cleaves the bait region, a conformational change is induced in the protein which traps the proteinase. The entrapped enzyme remains active against low molecular weight substrates (activity against high molecular weight substrates is greatly reduced). Following cleavage in the bait region a thioester bond is hydrolyzed and mediates the covalent binding of the protein to the proteinase.
Subunit:
Homotetramer, which consists of two pairs of disulfide-linked chains.
Subcellular Location:
Secreted.
Similarity:
Belongs to the protease inhibitor I39 (alpha-2-macroglobulin) family.

文献和实验X性联无丙种球蛋白血症(X-linked agammagl,bulinemia,XLA)是临床上首次确定的体液免疫缺陷病,由Brutor于1952年报道,故又称Bruton病。XLA作为常见的原发性免疫缺陷病之一,特点为血清中各类免疫球蛋白缺乏,或只能测得微量的抗体。外周血和淋巴组织中B细胞减少或完全缺乏,淋巴结中无生发中心和浆细胞。本病起病早,在出生数月后当患儿体内的母源性抗体水平下降时开始发病。临床表现为反复化脓性感染,患者细胞免疫功能不受影响(部分患者有T细胞数量减少),主要缺陷
抗体的结构 抗体是能与抗原特异性结合的免疫球蛋白(immunoglobulin,Ig)。Ig 分五类,即 IgG、IgA、IgM、IgD 和 IgE。与免疫测定有关的 Ig 主要为 IgG 和 IgM。Ig 由两个轻链(L)和两个重链(H)的单体组成。Ig 的轻链是相同的,有 κ(kappa)和 λ(Lambda)两种型别。五类 Ig 的重链结构不同,这决定了它们的抗原性也不同。IgG 和 IgM 的重链分别称为 γ(gamma)链和 μ(mu )链。 重链和轻链的 N 端的氨基酸排列顺序
就没有结合补体的能力。“天然抗体”通常是IgM免疫球蛋白,但有些“天然抗体”却是IgG免疫球蛋白。如有的抗Lea,抗M、抗N及抗K“天然抗体”是IgG。 免疫性抗体则是指机体受同种或异种抗原刺激后处于超免疫状态而产生的抗体。输血、妊娠是产生同种免疫抗体的主要原因。接受菌苗、抗血清(白喉、破伤风抗毒素)注射,以及使用过猪的胃、肝浸液的人,血清中的抗A、抗B效价升高,是异种免疫引起的免疫性抗体的例子。免疫性抗A及抗B,在许多方面与“天然抗体”不同(见表)。
