TM9 family proteins control surface targeting of glycine-rich transmembrane domains
TM9 family proteins (also named Phg1 proteins) have been previously shown to control cell adhesion by determining the cell surface localization of adhesion proteins such as the Dictyostelium SibA protein. Here, we show that the glycine-rich transmembrane domain (TMD) of SibA is sufficient to confer Phg1A-dependent surface targeting to a reporter protein.… (More)
Immunofluorescence labeling of cell surface antigens in Dictyostelium
Immunolocalization of cellular antigens typically requires fixation and permeabilization of cells, prior to incubation with antibodies. Assessing a test protein abundantly present at the cell surface of Dictyostelium cells, we show that in fixed cells, permeabilization extracts almost completely this cell surface antigen. The extent of this artifact is… (More)
MitoNEET-dependent formation of intermitochondrial junctions.
MitoNEET (mNEET) is a dimeric mitochondrial outer membrane protein implicated in many facets of human pathophysiology, notably diabetes and cancer, but its molecular function remains poorly characterized. In this study, we generated and analyzed mNEET KO cells and found that in these cells the mitochondrial network was disturbed. Analysis of 3D-EM… (More)
