Gp38k is a 383-amino-acid secreted glycoprotein expressed by cultured vascular smooth muscle cells during the time of transition from a proliferating monolayer culture to a nonproliferating multilayered (differentiated) culture. Expression continues as the cell culture forms multicellular nodules. Because this transition period involves active cell(More)
The tight junction constitutes the major barrier to solute and water flow through the paracellular space of epithelia and endothelia. It is formed by transmembrane proteins and submembranous molecules such as the MAGUKs ZOs. We have previously found that several MAGUKs, including those of the tight (ZO-1, ZO-2, and ZO-3) and septate junction (tamou and(More)
