Rho family GTPase The major activator of Rho family GTPase is GPCR (G-Protein coupled Receptor). GPCRs that activate Rho and use G-Alpha12 or G-Alpha13 for signal transduction include receptors for LPA (Lysophosphatidic Acid) and S-1P (Sphingosine 1-Phosphate) and certain Hormones. Besides GPCR, Itgs (Integrins) also activate Rho GTPase.

- Glycogen synthase (UDP-glucose-glycogen glucosyltransferase) is an enzyme involved in converting glucose to glycogen. It takes short polymers of glucose and converts them into long polymers of glycogen.n the other hand, much less is known about the structure of glycogen synthase, the key regulatory enzyme of glycogen synthesis. The crystal structure of glycogen synthase from Agrobacterium tumefaciens, however, has been determined at 2.3 A resolution.

Types of Frontotemporal Disorders Semantic variant Primary Progressive Aphasia. Primary progressive aphasia (PPA) is a language disorder that involves changes in the ability to speak, read, write and understand what others are saying. It is associated with a disease process that causes atrophy in the frontal and temporal areas of the brain, and is distinct from aphasia resulting from a stroke.

- Tissue plasminogen activator (abbreviated tPA or PLAT) is a protein involved in the breakdown of blood clots. It is a serine protease (EC 3.4.21.68) found on endothelial cells, the cells that line the blood vessels.t has been suggested that if tPA is effective in ischemic stroke, it must be administered as early as possible after the onset of stroke symptoms. Indeed, tPA has become widely considered standard of care in acute ischemic stroke, so long as the patient presents soon after the onset of stroke symptoms.

- About this test. Gamma GT or Gamma-glutamyl transferase is an enzyme that occurs in liver cells. A high Gamma GT level is particularly associated with heavy alcohol drinking. The liver breaks down and clears alcohol from the body and Gamma GT is involved in the process. How it works

tissue plasminogen activator tissue plasminogen activator (TPA) A natural body ENZYME involved in the breakdown of blood clots. TPA is a small molecule protease that activates the conversion of plasminogen to plasmin. Plasmin is an enzyme that can convert fibrin strands in the blood clot to soluble products so that blood clot can be dissolved.

Apoptosis: A Review of Programmed Cell Death A few possible mechanisms have been studied but none have been proven definitively. Mitochondrial damage in the Fas pathway of apoptosis is mediated by the caspase-8 cleavage of Bid (Li et al., 1998; Esposti, 2002).This is one example of the “cross-talk” between the death-receptor (extrinsic) pathway and the mitochondrial (intrinsic) pathway (Igney and Krammer, 2002).inally, apoptosis is a coordinated and often energy-dependent process that involves the activation of a group of cysteine proteases called “caspases” and a complex cascade of events that link the initiating stimuli to the final demise of the cell.

- The activation of Ras proteins, that is, the exchange of GDP with GTP, is an intrinsically slow process and is catalyzed by guanine nucleotide exchange factors (GEFs). However, this exchange is, in principle, reversible.

- GM1 gangliosidosis is one of over 50 different l ysosomal storage diseases. It is characterized by the lack of the enzyme, beta-galactisodase. The job of beta-galactisodase is to break down GM1, a type of fatty molecule called a lipid, that is an important component of normal nerve cells called neurons.

- Rab proteins, like all the GTPases of the Ras family, function as molecular switchs. In the active GTP-bound form Rab protein recruits soluble factors to relay the GTPase signal to downstream effector system/proteins, which respond to a specific Rab and mediates at least one element of the downstream effects.embrane-bound Rab GTP is stabilized by the recruitment of cytosolic effector proteins and regulates the activity of a downstream v/t-SNARE complex [73] and [104] . Upon GTP hydrolysis of the Rab protein, mediated by a GTPase Activating Protein (GAP), the active Rab is converted back to the GDP-bound form.

What Is Pancreatitis? The pancreas is a large gland behind the stomach and next to the small intestine. 1  It releases powerful digestive enzymes into the small intestine to aid the digestion of food.  It releases the hormones insulin and glucagon into the bloodstream. These hormones help the body control how it uses food for energy.

Greater trochanteric pain syndrome [edit on Wikidata] Greater trochanteric pain syndrome (GTPS), also known as trochanteric bursitis, is inflammation of the trochanteric bursa, a part of the hip. This bursa is at the top, outer side of the femur, between the insertion of the gluteus medius and gluteus minimus muscles into the greater trochanter of the femur and the femoral shaft.

Gingivostomatitis In Children What is gingivostomatitis (GS)? GS is a condition that causes painful sores on the lips, tongue, gums, and inside the mouth. GS is caused by the herpes simplex virus. The virus spreads easily through saliva, shared toys, drink cups, or eating utensils. The mouth sores make swallowing painful, so your child may not want to eat or drink. The sores usually heal within 2 weeks.

What is a Phospholipase? Phospholipases are defined by the enzymatic reaction they catalyze. The classes are phospholipase A, which has members A1 and A2; phospholipase B, which can carry out the reactions of both A1 and A2; phospholipase C; and phospholipase D. Phospholipase is usually abbreviated as PL. phospholipase is a member of a very complex group of enzymes that break down phospholipids into fatty acids and other compounds.

- As of November 2009, twelve caspases have been identified in humans. There are two types of apoptotic caspases: initiator (apical) caspases and effector (executioner) caspases. Initiator caspases (e.g., CASP2, CASP8, CASP9, and CASP10) cleave inactive pro-forms of effector caspases, thereby activating them.
