Integral membrane proteins specific to the inner nuclear membrane and associated with the nuclear lamina
We obtained a monoclonal antibody (RL13) that identifies three integral membrane proteins specific to the nuclear envelope of rat liver, a major 75-kD polypeptide and two more minor components of 68 and 55 kD. Immunogold labeling of isolated nuclear envelopes demonstrates that these antigens are localized specifically to the inner nuclear membrane, and that the RL13 epitope occurs on the inner ...
متن کاملLysosomal membrane proteins: life between acid and neutral conditions.
Whereas we have a profound understanding about the function and biogenesis of the protein constituents in the lumen of the lysosomal compartment, much less is known about the functions of proteins of the lysosomal membrane. Proteomic analyses of the lysosomal membrane suggest that, apart from the well-known lysosomal membrane proteins, additional and less abundant membrane proteins are present....

متن کاملCharacterization of lysosomal membrane proteins of Dictyostelium discoideum. A complex population of acidic integral membrane glycoproteins, Rab GTP-binding proteins and vacuolar ATPase subunits.
Highly purified lysosomes, prepared by magnetic fractionation of homogenates from Dictyostelium discoideum cells fed colloidal iron, were lysed under hypoosmotic conditions, and the membrane-associated proteins were subjected to gel electrophoresis. Thirteen major membrane polypeptides, ranging in molecular weight from 25,000 to 100,000 were identified. The isoelectric points of these proteins ...
متن کاملMembrane stiffness is modified by integral membrane proteins
The ease with which a cell membrane can bend and deform is important for a wide range of biological functions. Peripheral proteins that induce curvature in membranes (e.g. BAR domains) have been studied for a number of years. Little is known, however, about the effect of integral membrane proteins on the stiffness of a membrane (characterised by the bending rigidity, Kc). We demonstrate by comp...
