  1. › wiki › CollagenCollagen - Wikipedia

    From Wikipedia, the free encyclopedia. Tropocollagen molecule: three left-handed procollagens (red, green, blue) join to form a right-handed triple helical tropocollagen. Collagen ( / ˈkɒlədʒən /) is the main structural protein in the extracellular matrix found in the body's various connective tissues. As the main component of connective ...

    The COL1A1 gene produces the pro-alpha1(I) chain. This chain combines with another pro-alpha1(I) chain and also with a pro-alpha2(I) chain (produced by the COL1A2gene) to make a molecule of type I pro-collagen. These triple-stranded, rope-like pro-collagen molecules must be processed by enzymes outside the cell. Once these molecules are processed, ...

    See Collagen, type I, alpha 1#Clinical significance Markers used to measure bone loss are not easily testable. Degradation of type 1 collagen releases metabolites that can be used to monitor resorption.

  2. Type II collagen is the basis for articular cartilage and hyaline cartilage, formed by homotrimers of collagen, type II, alpha 1 chains. It makes up 50% of all protein in cartilage and 85–90% of collagen of articular cartilage. Type II collagen does form fibrils. This fibrillar network of collagen allows cartilage to entrap the proteoglycan ...

    The normal function of Aβ is not well understood. Though some animal studies have shown that the absence of Aβ does not lead to any obvious loss of physiological function, several potential activities have been discovered for Aβ, including activation of kinase enzymes, protection against oxidative stress, regulation of cholesterol transport, functi...

    Aβ is the main component of amyloid plaques, extracellular deposits found in the brains of people with Alzheimer's disease. Aβ can also form the deposits that line cerebral blood vessels in cerebral amyloid angiopathy. The plaques are composed of a tangle of Aβ oligomers and regularly ordered aggregates called amyloid fibrils, a protein fold shared...

    Aβ is formed after sequential cleavage of the amyloid precursor protein (APP), a transmembrane glycoprotein of undetermined function. APP can be cleaved by the proteolytic enzymes α-, β- and γ-secretase; Aβ protein is generated by successive action of the β and γ secretases. The γ secretase, which produces the C-terminal end of the Aβ peptide, clea...

    Autosomal-dominant mutations in APP cause hereditary early-onset Alzheimer's disease (familial AD, fAD). This form of AD accounts for no more than 10% of all cases, and the vast majority of AD is not accompanied by such mutations. However, familial Alzheimer's disease is likely to result from altered proteolytic processing. This is evidenced by the...

    Amyloid beta is commonly thought to be intrinsically unstructured, meaning that in solution it does not acquire a unique tertiary fold but rather populates a set of structures. As such, it cannot be crystallized and most structural knowledge on amyloid beta comes from NMR and molecular dynamics. Early NMR-derived models of a 26-aminoacid polypeptid...

    Researchers in Alzheimer's disease have identified several strategies as possible interventions against amyloid: 1. β-Secretase inhibitors. These work to block the first cleavage of APP inside of the cell, at the endoplasmic reticulum. 2. γ-Secretase inhibitors (e. g. semagacestat). These work to block the second cleavage of APP in the cell membran...

    Imaging compounds, notably Pittsburgh compound B, (6-OH-BTA-1, a thioflavin), can selectively bind to amyloid beta in vitro and in vivo. This technique, combined with PETimaging, is used to image areas of plaque deposits in those with Alzheimer's.

  4. › wiki › ProteinProtein - Wikipedia

    Proteins are assembled from amino acids using information encoded in genes. Each protein has its own unique amino acid sequence that is specified by the nucleotide sequence of the gene encoding this protein. The genetic code is a set of three-nucleotide sets called codons and each three-nucleotide combination designates an amino acid, for example AUG (adenine–uracil–guanine) is the code ...

  5. View/Edit Mouse. AH receptor-interacting protein ( AIP) also known as aryl hydrocarbon receptor-interacting protein, immunophilin homolog ARA9, or HBV X-associated protein 2 ( XAP-2) is a protein that in humans is encoded by the AIP gene. The protein is a member of the FKBP family.

  6. Absence of side effects is a necessary, but not sufficient, condition for referential transparency. Referential transparency means that an expression (such as a function call) can be replaced with its value. This requires that the expression is pure, that is to say the expression must be deterministic (always give the same value for the same input) and side-effect free.
