Intramembrane proteolytic cleavage of a membrane …
Regulated intramembrane proteolysis (RIP) involves cleavage of a transmembrane segment of a protein. RIP governs diverse processes in a wide variety of organisms and is carried out by different types of intramembrane proteases (IPs), including a large family of metalloproteases. The Bacillus subtilis SpoIVFB protein is a putative metalloprotease that cleaves membrane-tethered Pro-σK
Analysis on the cleavage of membrane-bound …
Betacellulin (BTC), a member of the epidermal growth factor (EGF) family, is synthesized as a membrane-bound form which is cleaved to a released form. This represents the switching juxtacrine function of BTC to paracrine. To analyze the mechanism of cleavage
Microcirculation Laboratory
Proteolytic cleavage of this receptor leads to reduced pseudopod retraction, as seen in hypertension and in the metabolic syndrome. The lack of shear stress response by cleaved membrane receptors leads to spontaneous pseodopod formation in circulating leukocytes, a phenomenon that strongly influences microvascular hemodynamics .

Protein cleavage strategies for an improved analysis of …
Background Membrane proteins still remain elusive in proteomic studies. This is in part due to the distribution of the amino acids lysine and arginine, which are less frequent in integral membrane proteins and almost absent in transmembrane helices. As these amino acids are cleavage targets for the commonly used protease trypsin, alternative cleavage conditions, which should improve membrane

Six membrane proteins were up-regulated more than twofold in the absence of SPP, of which only two were in a type II membrane orientation required for cleavage by SPP; Sec11c (see Fig. 3 B) and heme oxygenase (HO-1), the well-characterized rate-limiting).

G protein-coupled receptor
G protein-coupled receptors (GPCRs), also known as seven-(pass)-transmembrane domain receptors, 7TM receptors, heptahelical receptors, serpentine receptors, and G protein-linked receptors (GPLR), form a large group of evolutionarily-related proteins that are cell surface receptors that detect molecules outside the cell and activate cellular responses.
MMP2
As another example, cleavage of laminin-5, a component of the basement membrane, by MMP-2 has been shown to reveal a cryptic site inducing migration of breast epithelial cells. [21] More generally, by degrading the ECM, MMPs release growth factors that were previously bound to the ECM, allowing them to bind with cell receptors and influence cell signaling.

Cleavage of Amyloid-β Precursor Protein (APP) by …
MT3-MMP cleaves APP to generate membrane-anchored CTFs (), which might be susceptible to further cleavage by a γ-secretase. This may account for the enhancement of APP-Gal4–mediated transactivation by MT3-MMP.
3.2: Cell Division and Movement: Cleavage
Cleavage Cleavage stages of embryogenesis are typically very similar across animals. During cleavage a single cell embryo rapidly divides to form a ball of cells, called a blastula. This ball may be hollow inside, have a hollow region, or be fairly solid. Early cleavage
