Specific Rab GTPase-activating proteins define the Shiga toxin and epidermal growth factor uptake pathways [PDF]

, 2007
Rab family guanosine triphosphatases (GTPases) together with their regulators define specific pathways of membrane traffic within eukaryotic cells. In this study, we have investigated which Rab GTPase-activating proteins (GAPs) can interfere with the ...

Import pathways of precursor proteins into mitochondria [PDF]

, 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 ...

Analysis of outer membrane vesicle associated proteins isolated from the plant pathogenic bacterium Xanthomonas campestris pv. campestris

BMC Microbiology, 2008
Background Outer membrane vesicles (OMVs) are released from the outer membrane of many Gram-negative bacteria. These extracellular compartments are known to transport compounds involved in cell-cell signalling as well as virulence associated proteins, e ...

Distinct N-terminal regions of the exomer secretory vesicle cargo Chs3 regulate its trafficking itinerary

Frontiers in Cell and Developmental Biology, 2014
Cells transport integral membrane proteins between organelles by sorting them into vesicles. Cargo adaptors act to recognize sorting signals in transmembrane cargos and to interact with coat complexes that aid in vesicle biogenesis. No coat proteins have

Membrane proteins in the outer mebrane of plastids and mitochondria [PDF]

, 2006
Channels of the plastid and mitochondrial outer membranes facilitate the turnover of molecules and ions via these membranes. Although channels have been studied many questions pertaining to the whole diversity of plastid and mitochondrial channels in ...

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

, 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.

Ceramide-1-phosphate transfer protein enhances lipid transport by disrupting hydrophobic lipid–membrane contacts

PLoS Computational Biology, 2023
Cellular distributions of the sphingolipid ceramide-1-phosphate (C1P) impact essential biological processes. C1P levels are spatiotemporally regulated by ceramide-1-phosphate transfer protein (CPTP), which efficiently shuttles C1P between organelle ...

Immunological and biochemical characterization of the major seed oil-body membrane proteins [PDF]

, 1988
The major seed oil-body membrane proteins have been purified from a range of plant species by preparative SDS/PAGE, The purified proteins were used to elicit antibodies in rabbits and mice.

IDRs in Cross-Membrane Transport: Regulation of Ion Channels and Transporters, Mechanistic Studies Made Possible by NMR and Computational Methods

Frontiers in Biophysics
The roles of intrinsically disordered proteins (IDPs) and regions (IDRs) in health and disease have gained increasing attention in recent years. Understanding their structure–activity relationships remains challenging, especially for integral membrane ...
