Chloroplast precursor protein translocon [PDF]

FEBS Letters, 1999
Chloroplasts are believed to have originated from a photosynthetic, prokaryotic ancestor. As the result of endosymbiotic evolution, most of the genes of the endocytobiont were displaced to the host nucleus. Today's chloroplasts must import most of their proteins from the cytosol as precursors.

Biology and pathophysiology of the amyloid precursor protein [PDF]

Molecular Neurodegeneration, 2011
The amyloid precursor protein (APP) plays a central role in the pathophysiology of Alzheimer's disease in large part due to the sequential proteolytic cleavages that result in the generation of β-amyloid peptides (Aβ). Not surprisingly, the biological properties of APP have also been the subject of great interest and intense investigations.

Mitochondrial Protein Import [PDF]

, 1987
The role of nucleoside triphosphates (NTPs) in mitochondrial protein import was investigated with the precursors of N. crassa ADP/ATP carrier, F1-ATPase subunit β, F0-ATPase subunit 9, and fusion proteins between subunit 9 and mouse dihydrofolate ...

Amyloid precursor protein and amyloid precursor-like protein 2 in cancer

Oncotarget, 2016
Amyloid precursor protein (APP) and its family members amyloid precursor-like protein 1 (APLP1) and amyloid precursor-like protein 2 (APLP2) are type 1 transmembrane glycoproteins that are highly conserved across species. The transcriptional regulation of APP and APLP2 is similar but not identical, and the cleavage of both proteins is regulated by ...

Protein folding causes an arrest of preprotein translocation into mitochondria in vivo [PDF]

, 1991
With vital yeast cells, a hybrid protein consisting of the amino- terminal third of the precursor to cytochrome b2 and of the entire dihydrofolate reductase was arrested on the import pathway into mitochondria.

Early steps in mitochondrial protein import [PDF]

, 1990
The process of insertion of precursor proteins into mitochondrial membranes was investigated using a hybrid protein (pSc1-c) that contains dual targeting information and, at the same time, membrane insertion activity.

A morphological view on mitochondrial protein targeting [PDF]

, 1994
Mitochondrial protein targeting includes both intramitochondrial sorting of proteins encoded by the organellar genome and import and subsequent sorting of nuclear encoded precursor proteins. Only a few proteins are encoded by the mitochondrial genome and

Protein translocation across mitochondrial membranes [PDF]

, 1992
Protein translocation across biological membranes is of fundamental importance for the biogenesis of organelles and in protein secretion. We will give an overview of the recent achievements in the understanding of protein translocation across ...

Rrp47p is an exosome-associated protein required for the 3 ' processing of stable RNAs [PDF]

, 2003
Related exosome complexes of 3'-->5' exonucleases are present in the nucleus and the cytoplasm. Purification of exosome complexes from whole-cell lysates identified a Mg2+-labile factor present in substoichiometric amounts. This protein was identified

Neuroprotective Secreted Amyloid Precursor Protein Acts by Disrupting Amyloid Precursor Protein Dimers [PDF]

Journal of Biological Chemistry, 2009
The amyloid precursor protein (APP) is implied both in cell growth and differentiation and in neurodegenerative processes in Alzheimer disease. Regulated proteolysis of APP generates biologically active fragments such as the neuroprotective secreted ectodomain sAPPalpha and the neurotoxic beta-amyloid peptide.
