Alternative splicing produces three protein isoforms.Protein A includes all of the exons, whereas Proteins B and C result from exon skipping.. Alternative splicing, alternative RNA splicing, or differential splicing, is an alternative splicing process during gene expression that allows a single gene to produce different splice variants.
Protein A, B and C are isoforms encoded from the same gene through alternative splicing. A protein isoform, or "protein variant", [1] is a member of a set of highly similar proteins that originate from a single gene and are the result of genetic differences. [2] While many perform the same or similar biological roles, some isoforms have unique ...
Receptors may bind with some molecules (ligands) or may interact with physical agents like light, mechanical temperature, pressure, etc. Reception occurs when the target cell (any cell with a receptor protein specific to the signal molecule) detects a signal, usually in the form of a small, water-soluble molecule, via binding to a receptor ...
The majority of enzyme-linked receptors are, or associate with, protein kinases. G protein-coupled receptors are integral membrane proteins that possess seven transmembrane helices. These receptors activate a G protein upon agonist binding, and the G-protein mediates receptor effects on intracellular signaling pathways.
A molecule that binds to a receptor is called a ligand and can be a protein, peptide (short protein), or another small molecule, such as a neurotransmitter, hormone, pharmaceutical drug, toxin, calcium ion or parts of the outside of a virus or microbe. An endogenously produced substance that binds to a particular receptor is referred to as its ...
The endometrium houses stromal cells that will differentiate to produce an optimal environment for the embryo to attach (decidualization). OPN is a vital protein for stromal cell proliferation and differentiation as well as it binds to the receptor αvβ3 to assist with adhesion.
The B-cell receptor (BCR) is a transmembrane protein on the surface of a B cell. A B-cell receptor is composed of a membrane-bound immunoglobulin molecule and a signal transduction moiety. The former forms a type 1 transmembrane receptor protein, and is typically located on the outer surface of these lymphocyte cells. [1]
The notch receptor is a single-pass transmembrane receptor protein. It is a hetero-oligomer composed of a large extracellular portion, which associates in a calcium -dependent, non-covalent interaction with a smaller piece of the notch protein composed of a short extracellular region, a single transmembrane-pass, and a small intracellular region.
