The Targeting of Proteins to a Membrane That Occurs After Their Translation. Some Secretory Proteins Exhibit Posttranslational Transport Into the Endoplasmic Reticulum (er) Lumen: They Are Synthesized in Their Entirety On Free Cytosolic Ribosomes and Then Released Into the Cytosol Where They Are Bound by Chaperones Which Keep Them in an Unfolded State and Subsequently Are Translocated Across the Er Membrane.
The Directed Movement of Substances (such As Macromolecules Small Molecules Ions) Into Out of or Within a Cell or Between Cells or Within a Multicellular Organism by Means of Some Agent Such As a Transporter or Pore.
A Cellular Transport Process in Which Transported Substances Are Moved in Membrane Bounded Vesicles; Transported Substances Are Enclosed in the Vesicle Lumen or Located in the Vesicle Membrane. the Process Begins with a Step That Directs a Substance to the Forming Vesicle and Includes Vesicle Budding and Coating. Vesicles Are Then Targeted to and Fuse with an Acceptor Membrane.
The Process That Results in Incorporation of a Protein Into an Endoplasmic Reticulum (er) Membrane. It Depends On Specific Topogenic Sequences of Amino Acids That Ensure That a Protein Acquires the Proper Orientation During Its Insertion Into the Er Membrane.
An Er Membrane Insertion Complex That Contains Subunits That Recognize Two Types of Transmembrane Domain Signals. in Budding Yeast the Complex Contains Get4p Get5p Sgt2p and At Least Two Heat Shock Proteins (hsps).
Coexpressed with Yor164c. After Affinity Purification Limited Proteolysis Was Performed with Chymotrypsin. the Major Fragments Were Separated by Anion Exchange Chromatography Followed by Crystallization.
