During early stages of development of the vertebrate central nervous system, neural precursors divide symmetrically to produce new precursors, thereby expanding the precursor population. During middle stages of neural development, precursors switch to an asymmetric division pattern whereby each mitosis produces one new precursor and one cell that differentiates as a neuron or glial cell. At lat...
The Tim9-Tim10 complex plays an essential role in mitochondrial protein import by chaperoning select hydrophobic precursor proteins across the intermembrane space. How the complex interacts with precursors is not clear, although it has been proposed that Tim10 acts in substrate recognition, whereas Tim9 acts in complex stabilization. In this study, we report the structure of the yeast Tim9-Tim1...
It is well established that binding of p120 catenin to the cytoplasmic domain of surface cadherin prevents cadherin endocytosis and degradation, contributing to cell-cell adhesion. In the present work we show that p120 catenin bound to the N-cadherin precursor, contributes to its anterograde movement from the endoplasmic reticulum (ER) to the Golgi complex. In HeLa cells, depletion of p120 expr...
The thylakoid DeltapH-dependent/Tat pathway is a novel system with the remarkable ability to transport tightly folded precursor proteins using a transmembrane DeltapH as the sole energy source. Three known components of the transport machinery exist in two distinct subcomplexes. A cpTatC-Hcf106 complex serves as precursor receptor and a Tha4 complex is required after precursor recognition. Here...
The interactions of precursor proteins with components of the chloroplast envelope were investigated during the early stages of protein import using a chemical cross-linking strategy. In the absence of energy, two components of the outer envelope import machinery, IAP86 and IAP75, cross-linked to the transit sequence of the precursor to the small subunit of ribulose-1, 5-bisphosphate carboxylas...
developing reliable and eco-friendly processes for the synthesis of metallic nanoparticles is an essential step in the field of application of nanotechnology .using natural factories such as biological systems is a way of developing such processes. nowadays, the synthesis of silver nanoparticles is very common due to its numerous applications in different fields. the synthesis of these nanopart...
alteration of alzheimer amyloid precursor protein after treatment with carbamazepine in colon cancer
conclusions the results of this study suggest that app reduction by hdacis can apparently play an important role in the treatment of colon cancer. background amyloid precursor protein (app), which is involved in cell proliferation, is observed to be over expressed in human cancer. thus, it is crucial to investigate its role in cancer and suggest treatment strategies to alter its effects on cell...
