まとめ
プロテオリシス標的キメラ(PROTAC)D072は、ブロモドメイン・アンド・エクストリミナル(BET)タンパク質BRD3を分解することにより、眼内炎症を軽減する。この標的アプローチは、炎症促進性ミクログリアを阻害し、自己免疫性ぶどう膜炎の新たな治療法となる可能性を秘めている。
背景:
- ぶどう膜炎は視力を脅かす眼内炎症である。
- 網膜ミクログリアからの炎症促進性免疫応答は、ぶどう膜炎の主要な駆動因子である。
- ブロモドメイン・アンド・エクストリミナル(BET)タンパク質を標的とするプロテオリシス標的キメラ(PROTAC)のぶどう膜炎における治療可能性は、ほとんど探求されていない。
結論:
- PROTAC D072は、自己免疫性ぶどう膜炎における炎症促進性ミクログリアを阻害する効果的な特異的BRD3分解剤である。
- BRD3の標的分解は、ぶどう膜炎管理のための有望な治療戦略を提示する。

Regulated Protein Degradation
8.8K
It is vital to regulate the activity of enzymatic as well as non-enzymatic proteins inside the cell. This can be achieved either through creating a balance between their rate of synthesis and degradation or regulating the intrinsic activity of the protein. Both these regulation mechanisms play an essential role in the normal functioning of cells.
Protein degradation plays two important roles in the cells. It helps to protect cells from misfolded or damaged proteins before they lead to a...

Proteins: From Genes to Degradation
14.3K
Within a biological system, the DNA encodes the RNA, and the nucleotide sequence in the RNA further defines the amino acid sequence in the protein. This is referred to as “The Central Dogma of Molecular Biology” - a term coined by Francis Crick. Central dogma is a firm principle in biology that defines the flow of genetic information within any life form. The two fundamental steps in central dogma are - transcription and translation.

ATP Driven Pumps I: An Overview
9.8K
ATP-driven pumps, also known as transport ATPases, are integral membrane proteins. They have binding sites for ATP located on the membrane's cytosolic side and the ion-conducting domain in the transmembrane region. These pumps use the free energy released from ATP hydrolysis to move the solutes across cell membranes against an electrochemical gradient.
There are four main types of ATP-driven pumps - P-type, V-type, F-type, and ABC transporter. All these pumps are of varying complexities and...

Role of Matrix Metalloproteases in Degradation of ECM
3.3K
Matrix metalloproteases (MMPs) are enzymes involved in the hydrolysis of proteins and glycoproteins of the extracellular matrix. MMPs are essential for the migration and proliferation of cells through the dense matrix network, throughout embryonic development, and throughout morphogenesis. The first MMP activity discovered was a collagenase in a tadpole's tail undergoing metamorphosis. The active collagen deposition and modifications lead to the morphogenesis of tadpoles into the adult...
