Proper insertion and topogenesis of membrane proteins in the ER depends on Sec63.

Summary of "Proper insertion and topogenesis of membrane proteins in the ER depends on Sec63."

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.

Medical and Biotech [MESH] Definitions

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.
