Early steps in mitochondrial protein import [PDF]

open access: yes, 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.

Origins, function and regulation of the TOC-TIC general protein import machinery of plastids.

open access: yesJournal of Experimental Botany, 2019
The evolution of chloroplasts from the original endosymbiont involved the transfer of thousands of genes from the ancestral bacterial genome to the host nucleus, thereby combining the two genetic systems to facilitate coordination of gene expression and ...

Surveying the floodgates: Estimating protein flux into the endoplasmic reticulum lumen in Saccharomyces cerevisiae

open access: yesFrontiers in Physiology, 2014
Endoplasmic reticulum resident proteins, along with all proteins traveling through the secretory pathway must enter endoplasmic reticulum lumen through membrane-embedded translocons.

Evolution of mitochondrial protein import – lessons from trypanosomes

open access: yesBiological chemistry, 2019
The evolution of mitochondrial protein import and the systems that mediate it marks the boundary between the endosymbiotic ancestor of mitochondria and a true organelle that is under the control of the nucleus.

Dual targeting of peroxisomal proteins

open access: yesFrontiers in Physiology, 2013
Cellular compartmentalization into organelles serves to separate biological processes within the environment of a single cell. While some metabolic reactions are specific to a single organelle, others occur in more than one cellular compartment. Specific

Defective mitochondrial protein import contributes to complex I-induced mitochondrial dysfunction and neurodegeneration in Parkinson’s disease

open access: yesCell Death and Disease, 2018
Mitochondria are the prime energy source in most eukaryotic cells, but these highly dynamic organelles are also involved in a multitude of cellular events.

Antifolding activity of hsp60 couples protein import into the mitochondrial matrix with export to the intermembrane space [PDF]

open access: yes, 1992
Cytochrome b2 reaches the intermembrane space of mitochondria by transport into the matrix followed by export across the inner membrane. While in the matrix, the protein interacts with hsp60, which arrests its folding prior to export.

The peroxisomal protein import machinery [PDF]

open access: yesFEBS Letters, 2007
Peroxisomes are unique organelles whose physiological functions vary depending on the cellular environment or metabolic and developmental state of the organism. These changes in enzyme content are accomplished by the dynamically operating membrane and matrix protein import machineries of peroxisomes that rely on the concerted function of at least 20 ...

Functional specialization amongst the Arabidopsis Toc159 family of chloroplast protein import receptors [PDF]

open access: yes, 2004
The initial stages of preprotein import into chloroplasts are mediated by the receptor GTPase Toc159. In Arabidopsis thaliana, Toc159 is encoded by a small gene family: atTOC159, atTOC132, atTOC120, and atTOC90.

Import pathways of precursor proteins into mitochondria [PDF]

open access: yes, 1988
The precursor of porin, a mitochondrial outer membrane protein, competes for the import of precursors destined for the three other mitochondrial compartments, including the Fe/S protein of the bc1- complex (intermembrane space), the ADP/ATP carrier ...
