描述 | The Tight Junction Antibody Sampler Kit provides an economical means to evaluate the presence of a number of proteins involved in tight junctions. The kit contains enough primary antibodies to perform four western blot experiments per primary antibody. |
目标/特异性 | CD2AP Antibody recognizes endogenous levels of total CD2AP protein. Claudin-1 Antibody recognizes endogenous levels of total claudin-1 protein. Based on sequence similarity, Claudin-1 Antibody may cross-react with claudin-2 protein. Occludin (D15G7) Rabbit mAb recognizes endogenous levels of total occludin protein. ZO-1 (D7D12) Rabbit mAb recognizes endogenous levels of total ZO-1 protein. ZO-2 Antibody recognizes endogenous levels of total ZO-2 protein. ZO-3 (D57G7) XP® Rabbit mAb detects endogenous levels of total ZO-3 protein. |

背景 | Tight junctions, or zona occludens, form a continuous barrier to fluids across the epithelium and endothelium. They function in regulation of paracellular permeability and in the maintenance of cell polarity, blocking the movement of transmembrane proteins between the apical and basolateral cell surfaces (reviewed in 1). Tight junctions are composed of claudin and occludin transmembrane proteins, which join the junctions to the cytoskeleton (1,2). Occludin is thought to be important in the assembly and maintenance of tight junctions. Differential phosphorylation of occludin at various residues may regulate its interaction with other tight junction proteins such as ZO-1 (3). Zona occludens proteins ZO-1, -2, and -3 (also known as TJP1, 2, and 3) are peripheral membrane adaptor proteins that link junctional transmembrane proteins such as occludin and claudin to the actin cytoskeleton (reviewed in 4). ZO-1 and ZO-2 are required for tight junction formation and function (5,6). In subconfluent proliferating cells, ZO-1 and ZO-2 have been shown to colocalize to the nucleus and play a role in transcriptional regulation (7-9). Exogenous expression of the amino terminal portion of ZO-3 exerts a dominant negative effect that interferes with assembly of tight junctions and adherens junctions (10). CD2AP is a scaffolding protein that is thought to link membrane proteins to the cytoskeleton (11-13). It plays a role in formation of tight junctions in specialized cell types such as the slit diaphragm in the kidney glomerulus (14). CD2AP is also involved in the immunological synapse between CD2-expressing T cells and antigen presenting cells (15). It has been shown that interaction between CD2AP and other cytoskeletal proteins may regulate the endocytosis of EGFR (13). |
