Importance of  -defensins in sperm function [PDF]

Molecular Human Reproduction, 2014
Recent work in humans and mouse has confirmed the involvement of the host defence β-defensin peptides in male fertility. We discuss here the work that has implicated β-defensins in sperm function including the identification of the epididymis as the predominant site of expression of the peptides and the in vivo consequences of mutation and deletion ...

A mitochondrial import receptor for the ADP/ATP carrier [PDF]

, 1990
We have identified a mitochondrial outer membrane protein of 72 kd (MOM72) that exhibits the properties of an import receptor for the ADP/ATP carrier (AAC), the most abundant mitochondrial protein.

A crucial role of the mitochondrial protein import receptor MOM19 for the biogenesis of mitochondria [PDF]

, 1994
The novel genetic method of "sheltered RIP" (repeat induced point mutation) was used to generate a Neurospora crassa mutant in which MOM19, a component of the protein import machinery of the mitochondrial outer membrane, can be depleted.

Characterisation of components and mechanisms involved in redox-regulation of protein import into chloroplasts [PDF]

, 2009
The vast majority of chloroplast proteins is encoded in the nucleus and thus has to be posttranslationally imported into the organelle, a process that is facilitated by two multimeric protein machineries, the Toc and Tic complexes (translocon at the ...

Protein import into chloroplasts: new aspects of a well-known topic [PDF]

, 2007
Protein import into plant chloroplasts is a fascinating topic that is being investigated by many research groups. Since the majority of chloroplast proteins are synthesised as precursor proteins in the cytosol, they have to be posttranslationally ...

Structural mapping of mitochondrial co-translational import in cells [PDF]

Structural Dynamics
Despite containing their own distinct genome, mitochondria rely heavily on the nucleus to encode 99% of the proteins necessary for mitochondrial function.

On the importance of the megabiota to the functioning of the biosphere

, 2019
A prominent signal of the Anthropocene is the extinction and population reduction of the megabiota – the largest animals and plants on the planet. However, we lack a predictive framework for the sensitivity of megabiota during times of rapid global change and how they impact the functioning of ecosystems and the biosphere.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Import of ADP/ATP carrier into mitochondria [PDF]

, 1990
We have identified the yeast homologue of Neurospora crassa MOM72, the mitochondrial import receptor for the ADP/ATP carrier (AAC), by functional studies and by cDNA sequencing.

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 ...
