A 69kD fusion protein corresponding to aa463-1109 of human ZO-1 cDNA. This sequence lies from the N-terminal to the 80aa region (the alpha-motif) present in the a+isoform but absent in the alpha- isoform due to alternative splicing.
MaxLight(TM) 650 is a new Far-IR stable dye conjugate comparable to Alexa Fluor(TM)647, DyLight(TM)649, Cy5(TM) and offers better labeling efficiency, brighter imaging and increased immunodetection. Absorbance (655nm), Emission (676nm), Extinction Coefficient 250,000. ZO-1 is a peripheral membrane protein that is associated with tight junctions (zonula occludentes) which are found on the cytoplasmic surface of epithelial and endothelial cell membranes. ZO-1 has a MW of 225kD and is found in two isoforms that differ by the presence or absence of an 80 amino acid region known as motif-a. These two isoforms are the basis for determining two classes of tight junctions. ZO-1 is known to interact with ZO-2. ZO-1 is homologous to dlg, the Drosophila tumor suppressor. Both are members of a putative signal transduction protein family whose members contain a SH3 domain and a domain homologous to the enzyme guanylate kinase.
