摘要:凝血因子XIII是一种血浆转谷氨酰胺酶。谷氨酰胺转氨酶是至少8种酶,它能使许多蛋白质发生交叉反应。这种类型的反应不仅增强了底物蛋白质的原有功能,而且还为它们增加了新的功能。血浆中的XIII因子是一个四聚体(A2B2),A亚基含有活性部位。虽然转谷氨酰胺酶是同源的,但它们5‘侧翼区的核苷酸序列有显著差异。因此,转录因子在每种转谷氨酰胺酶的细胞类型特异性表达中起主要作用。在凝血因子XIII缺乏症的A和B亚基基因中,已经发现了各种错义和无义突变,以及伴有或不伴有框外移位/提前终止和剪接异常的缺失/插入。在某些情况下,A或B亚基的mRNA水平严重降低。分子和细胞的碱基也已经通过表达实验和分子模拟来探索。在大多数情况下,突变的A或B亚基的折叠和/或构象改变受损会导致细胞内和细胞外的不稳定,这是导致XIII因子缺乏的原因。
Summary Factor XIII is a plasma transglutaminase. Transglutaminases are at least 8 enzymes which cross-link a number of proteins. This type of reaction not only enhances the original functions of substrate proteins, but also adds new functions to them. Factor XIII in plasma is a tetramer (A2B2), and the A subunit contains the active site. Although transglutaminases are homologous, the nucleotide sequences in their 5’-flanking region differ significantly. Accordingly, transcription factors play a major role in the cell type-specific expression of each transglutaminase. A variety of missense and nonsense mutations, and deletions/insertions with or without out-of-frame shift/premature termination and splicing abnormalities have been identified in the genes for A and B subunits in factor XIII deficiency. In some cases, the mRNA level of the A or B subunit was severely reduced. Molecular and cellular bases have also been explored by expression experiments and by molecular modeling. In most cases, impaired folding and/or conformational change of the mutant A or B subunit leads to both intra- and extra-cellular instability, which is responsible for factor XIII deficiency.
