产品介绍
胞质紧密粘连蛋白1（ZO-1）是多结构域蛋白家族膜结合鸟苷酸激酶的家族成员，在紧密连接蛋白的组成成分中起到对组织分化和器官形成方面起较重要的作用。ZO-1在包括肾、胎盘、血脑屏障等许多组织都有不同的表达，可与紧密连接上的很多跨膜蛋白相互作用。也有学者认为：ZO-1的改变与细胞通透性的增加有关。
背景资料
This gene encodes a member of the membrane-associated guanylate kinase (MAGUK) family of proteins, and acts as a tight junction adaptor protein that also regulates adherens junctions. Tight junctions regulate the movement of ions and macromolecules between endothelial and epithelial cells. The multidomain structure of this scaffold protein, including a postsynaptic density 95/disc-large/zona occludens (PDZ) domain, a Src homology (SH3) domain, a guanylate kinase (GuK) domain and unique (U) motifs all help to co-ordinate binding of transmembrane proteins, cytosolic proteins, and F-actin, which are required for tight junction function. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Aug 2017]

蛋白名
Tight junction protein ZO-1
亚基
Interacts with BVES (via the C-terminus cytoplasmic tail). Interacts with HSPA4 and KIRREL1. Homodimer, and heterodimer with TJP2/ZO-2 and TJP3/ZO-3. Interacts with OCLN, CALM, claudins, CGN/cingulin, CXADR, GJA12, GJD3 and UBN1. Interacts (via ZU5 domain) with CDC42BPB and MYZAP. Interacts (via PDZ domain) with GJA1.
亚细胞定位
Cell membrane; Peripheral membrane protein; Cytoplasmic side. Cell junction, tight junction. Cell junction. Cell junction, gap junction. Note=Moves from the cytoplasm to the cell membrane concurrently with cell-cell contact. Detected at the leading edge of migrating and wounded cells.
组织特异性
The alpha-containing isoform is found in most epithelial cell junctions. The short isoform is found both in endothelial cells and the highly specialized epithelial junctions of renal glomeruli and Sertoli cells of the seminiferous tubules.
翻译后修饰
Phosphorylated. Dephosphorylated by PTPRJ.
相似性
Belongs to the MAGUK family.
Contains 1 guanylate kinase-like domain.
Contains 3 PDZ (DHR) domains.
Contains 1 SH3 domain.
Contains 1 ZU5 domain.
Contains 1 guanylate kinase-like domain.
Contains 3 PDZ (DHR) domains.
Contains 1 SH3 domain.
Contains 1 ZU5 domain.
功能
The N-terminal may be involved in transducing a signal required for tight junction assembly, while the C-terminal may have specific properties of tight junctions. The alpha domain might be involved in stabilizing junctions. Plays a role in the regulation of cell migration by targeting CDC42BPB to the leading edge of migrating cells.
