MaxLight™ 490 is a new Blue-Green photostable dye conjugate comparable to DyLight™488, Alexa Fluor™488 and offers better labeling efficiency, brighter imaging and increased immunodetection.
ZO-3, a ~130kD protein, contains three PSD-95/SAP90, discs-large, ZO-1 (PDZ) domains, a SH3 domain, and a guanylate kinase-liked domain.
Like ZO-1 and ZO-2, ZO-3 contains a C-terminal acidic domain and a basic region (between the first and second PDZ domains), making it belongs to the MAGUK protein family.
By Western Blot analysis, ZO-3 is identified as a ~130kD protein that directly interacts with tight junction proteins ZO-1 and occuldin, but not with ZO-2.
However, in one study, ZO-2, ZO-3 and Occludin colocalized with actin aggregates at cell border in MDCK cells.
ZO-3 is localized to sites of cell-cell interaction, identical to that of ZO-1 in tight junctions.
By immunoprecipitation analysis, ZO-3 co-immunoprecipitates with ZO-1.
Using MDCK cells, ZO-3 protein colocalized with ZO-1 by immunofluorescence.
In vitro binding assays, the N-terminal of ZO-3 showed preferably binding of ZO-1 and actin filaments (3).
Moreover, the binding of ZO-1/ZO-2/ZO-3 was also found to interact with certain Claudin proteins.
