摘要: 凝血因子ⅩⅢ(FⅩⅢ)是血浆转谷氨酰胺酶家族的一员。在血浆中FⅩⅢ(pFⅩⅢ)由2个催化性A亚基及2个非催化性B亚基以非共价键结合形成异源四聚体(FⅩⅢ-A2B2)。在细胞内,FⅩⅢ以A亚单位同源二聚体(FⅩⅢ-A2)形式存在。虽然目前认为细胞内FⅩⅢ(cFⅩⅢ)可以通过一种未知的机制从细胞内外化,并交联细胞外底物从而参与多种的病理生理过程,其具体的功能和机制还需要系统的研究来阐明。

Abstract: Coagulation factor ⅩⅢ (FⅩⅢ) is a member of the plasma transglutaminase family.Plasma FⅩⅢ (pFⅩⅢ)consists of two catalytic A subunits and two non-catalytic B subunits(FⅩⅢ-A2B2)combined with non-covalent bonds to form a heterotetramer.The cellular FⅩⅢ(cFⅩⅢ) exists in a form of A subunit homodimer(FⅩⅢ-A2).Although it is currently believed that cellular FⅩⅢ can be internalized and externalized from the cell through an unknown mechanism and cross-linked extracellular substrates to function in a variety of pathophysiological events,its specific functions and mechanisms need to be clarified by further systematic research.

Key words: cellular coagulation factor ⅩⅢ, haemostasis, phagocytosis, inflammation
