Triple-helical collagen IV protomers associate through their N- and C-termini, forming a three-dimensional network that provides basement membranes with mechanical strength. Within this network, the C-terminal non-collagenous (NC1) domains ...
Efficient production of native actin upon translation in a bacterial lysate supplemented with the eukaryotic chaperonin TRiC [0.03%]
一种高效原核细胞裂解体系利用真核分子伴侣TRiC辅助表达纯化全长人源G-actin蛋白质的新方法

Recombinant expression of actin in bacteria results in non-native species that aggregate into inclusion bodies. Actin is a folding substrate of TRiC, the chaperonin of the eukaryotic cytosol. By employing bacterial in vitro translation lysa...

The flexibility of chromatin that enables translation of environmental cues into changes in genome utilisation, relies on a battery of enzymes able to modulate chromatin structure in a highly targeted and regulated manner. The most dynamic ...

Cell survival under severe thermal stress requires the activity of a bi-chaperone system, consisting of the ring-forming AAA+ chaperone ClpB (Hsp104) and the DnaK (Hsp70) chaperone system, which acts to solubilize and reactivate aggregated ...

The proteasome is a compartmentalized, ATP-dependent protease composed of more than 30 subunits that recognizes and degrades polyubiquitinated substrates. Despite its physiological importance, many aspects of the proteasome's structural org...
Splicing of a rare class of introns by the U12-dependent spliceosome [0.03%]

Pre-mRNA splicing is catalyzed by two unique spliceosomes, designated U2- or U12-dependent. In contrast to the well-characterized U2-dependent spliceosome, much remains to be learned about the less abundant U12-type spliceosome. This review...

Activation processing of cathepsin H impairs recognition by its propeptide [0.03%]
猫hepsin H的活化加工影响其前肽的识别作用

Free propeptides are known to function as inhibitors of the parental mature cysteine cathepsins. This general rule, however, does not apply to the aminopeptidase cathepsin H. Screening of propeptide fragments for their inhibitory potency re...
Inhibition of cathepsin B reduces beta-amyloid production in regulated secretory vesicles of neuronal chromaffin cells: evidence for cathepsin B as a candidate beta-secretase of Alzheimer's disease [0.03%]
猫肉豆蔻B抑制可减少神经肾上腺素能细胞调节分泌囊泡中β-淀粉样蛋白的产生:猫肉豆蔻B是阿尔茨海默氏病β-分泌酶候选者的证据

The regulated secretory pathway of neurons is the major source of extracellular A beta that accumulates in Alzheimer's disease (AD). Extracellular A beta secreted from that pathway is generated by beta-secretase processing of amyloid precur...
Focal adhesion kinase is redistributed to focal complexes and mediates cell spreading in macrophages in response to M-CSF [0.03%]
