まとめ
S129リン酸化αシヌクレイン線維はC末端の力学性を低下させ、共シャペロンDNAJB1との結合を強化し、神経変性疾患研究におけるシャペロン認識を助ける。
背景:
- αシヌクレイン(α-synuclein)アミロイド線維はシヌクレイン症の中心である。; 線維表面の固有の無秩序領域は、シャペロンなどの細胞成分との相互作用を媒介する。; シャペロンは、神経変性疾患におけるアミロイド形成の予防と逆転に不可欠である。
結論:
- αシヌクレイン線維におけるS129リン酸化は、表面の力学性を低下させ、DNAJB1を介してシャペロン認識を増加させるという二重の役割を果たす。; この修飾は、シヌクレイン症におけるシャペロン関与の重要なメカニズムである可能性がある。; この発見は、神経変性疾患のシャペロン媒介性分解経路に関する洞察を提供する。

Phosphorylation
53.8K
The addition or removal of phosphate groups from proteins is the most common chemical modification that regulates cellular processes. These modifications can affect the structure, activity, stability, and localization of proteins within cells as well as their interactions with other proteins.
During phosphorylation, protein kinases transfer the terminal phosphate group of ATP to specific amino acid side chains of substrate proteins. Serine, threonine, and tyrosine are the most commonly...

Amyloid Fibrils
11.9K
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...

Metallic Solids
20.6K
Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability....

Structures of Solids
17.7K
Solids in which the atoms, ions, or molecules are arranged in a definite repeating pattern are known as crystalline solids. Metals and ionic compounds typically form ordered, crystalline solids. A crystalline solid has a precise melting temperature because each atom or molecule of the same type is held in place with the same forces or energy. Amorphous solids or non-crystalline solids (or, sometimes, glasses) which lack an ordered internal structure and are randomly arranged. Substances that...

Fibril-associated Collagen
3.4K
Fibril-associated collagens are a type of collagens present in the extracellular matrix with interrupted triple helices or FACIT (Fibril-associated collagens interrupted triple-helices). FACIT help connect and attach the collagen fibrils with each other as well as with other proteins of the extracellular matrix.
For example, the type II collagen fibrils in cartilage have covalently bound type IX fibril-associated collagens at regular intervals. Other types of fibril-associated collagens are...
