In eukaryotic cells, biogenesis of proteins destined to the secretory pathway begins from the cytosol. Nascent chains are either co-translationally or post-translationally targeted to the endoplasmic reticulum (ER) and translocated across the membrane through the Sec61 complex. For the post-translational translocation, the Sec62/Sec63 complex is additionally required. Sec63, however, is also shown to mediate co-translational translocation of a subset of proteins, the types and characteristics of proteins that Sec63 mediates in translocation still awaits to be defined.

Most membrane proteins are composed of hydrophobic α-helical transmembrane segments and are integrated into the lipid bilayer of the endoplasmic reticulum by the highly conserved Sec61 translocon. Wi...
Sterols have been reported to modulate conformation and hence the function of several membrane proteins. One such group is the Chloride Intracellular Ion Channel (CLIC) family of proteins. The CLIC pr...
The peroxisomal membrane protein Pex3 and its cytosolic interaction partner Pex19 have been implicated in peroxisomal membrane biogenesis. Although these peroxins have been extensively studied, no con...
The proteome of the outer membrane of mitochondria and chloroplasts consists of membrane proteins anchored by α-helical or β-sheet elements. While proteins with α-helical transmembrane domains are ...
Peripheral membrane proteins associate reversibly with biological membranes that, compared to protein binding partners, are structurally labile and devoid of specific binding pockets. Membranes in dif...
IUD can cause pain and discomfort in several ways: Use of the tenaculum to grasp the cervix and straighten the uterus for proper insertion; trans-cervical actions including measuring uteri...
A current trend in dialysis membrane engineering is to maximize the permeability for larger low-molecular weight proteins while retaining albumin. Protein-leaking dialysis membranes do not...

Groups of study: 120 candidates for Cu T 380A IUD insertion were enrolled in the study. They were divided into two groups: Group 1: Sixty women received 600 micrograms of misoprostol vagi...
To determine the utility of ultrasound guided IUD insertion compared to the traditional blind insertion at an academic health institute where the skill level of the provider can vary great...
Proteins which are found in membranes including cellular and intracellular membranes. They consist of two types, peripheral and integral proteins. They include most membrane-associated enzymes, antigenic proteins, transport proteins, and drug, hormone, and lectin receptors.
A group of membrane transport proteins that transport biogenic amine derivatives of catechol across the PLASMA MEMBRANE. Catecholamine plasma membrane transporter proteins regulate neural transmission as well as catecholamine metabolism and recycling.
Membrane proteins encoded by the BCL-2 GENES and serving as potent inhibitors of cell death by APOPTOSIS. The proteins are found on mitochondrial, microsomal, and NUCLEAR MEMBRANE sites within many cell types. Overexpression of bcl-2 proteins, due to a translocation of the gene, is associated with follicular lymphoma.
Membrane proteins whose primary function is to facilitate the transport of molecules across a biological membrane. Included in this broad category are proteins involved in active transport (BIOLOGICAL TRANSPORT, ACTIVE), facilitated transport and ION CHANNELS.
Signaling proteins that are ligands for the EPH FAMILY RECEPTORS. They are membrane-bound proteins that are attached to the CELL MEMBRANE either through a GLYCOINOSITOL PHOSPHOLIPID MEMBRANE ANCHOR or through a transmembrane domain. Many of the ephrins are considered important intercellular signaling molecules that control morphogenic changes during embryogenesis.
