CJ Marques, T Francisco, S Sousa, F Carvalho… - Fertility and sterility, 2010 - Elsevier
OBJECTIVE: To study the methylation imprinting marks of two oppositely imprinted genes,
H19 and MEST/PEG1, in human testicular spermatozoa from azoospermic patients with …

Identification of ubiquitin-specific protease 9X (USP9X) as a deubiquitinase acting on ubiquitin-peroxin 5 (PEX5) thioester conjugate

CP Grou, T Francisco, TA Rodrigues, MO Freitas… - Journal of Biological …, 2012 - jbc.org
Peroxin 5 (PEX5), the peroxisomal protein shuttling receptor, binds newly synthesized
peroxisomal matrix proteins in the cytosol and promotes their translocation across the organelle …

[HTML][HTML] PEX5 protein binds monomeric catalase blocking its tetramerization and releases it upon binding the N-terminal domain of PEX14

MO Freitas, T Francisco, TA Rodrigues… - Journal of biological …, 2011 - Elsevier
Newly synthesized peroxisomal matrix proteins are targeted to the organelle by PEX5. PEX5
has a dual role in this process. First, it acts as a soluble receptor recognizing these proteins …

Export-deficient monoubiquitinated PEX5 triggers peroxisome removal in SV40 large T antigen-transformed mouse embryonic fibroblasts

M Nordgren, T Francisco, C Lismont, L Hennebel… - Autophagy, 2015 - Taylor & Francis
Peroxisomes are ubiquitous cell organelles essential for human health. To maintain a healthy
cellular environment, dysfunctional and superfluous peroxisomes need to be selectively …

Protein transport into peroxisomes: Knowns and unknowns

T Francisco, TA Rodrigues, AF Dias… - …, 2017 - Wiley Online Library
Peroxisomal matrix proteins are synthesized on cytosolic ribosomes and rapidly transported
into the organelle by a complex machinery. The data gathered in recent years suggest that …

Peroxisomal monoubiquitinated PEX5 interacts with the AAA ATPases PEX1 and PEX6 and is unfolded during its dislocation into the cytosol

AG Pedrosa, T Francisco, D Bicho, AF Dias… - Journal of Biological …, 2018 - jbc.org
PEX1 and PEX6 are two members of the ATPases associated with diverse cellular activities
(AAA) family and the core components of the receptor export module of the peroxisomal …

[HTML][HTML] The mammalian peroxisomal membrane is permeable to both GSH and GSSG–Implications for intraperoxisomal redox homeostasis

…, AG Pedrosa, L Gales, A Salvador, T Francisco… - Redox Biology, 2023 - Elsevier
Despite the large amounts of H 2 O 2 generated in mammalian peroxisomes, cysteine residues
of intraperoxisomal proteins are maintained in a reduced state. The biochemistry behind …

A cargo-centered perspective on the PEX5 receptor-mediated peroxisomal protein import pathway

T Francisco, TA Rodrigues, MO Freitas, CP Grou… - Journal of Biological …, 2013 - jbc.org
Background: How the soluble receptor PEX5 delivers its cargoes to the peroxisome remains
largely unknown. Results: Cargo translocation occurs after docking of the receptor at the …

Membrane topologies of PEX 13 and PEX 14 provide new insights on the mechanism of protein import into peroxisomes

…, CP Grou, MP Pinto, M Fransen, T Francisco… - The FEBS …, 2019 - Wiley Online Library
PEX 13 and PEX 14 are two core components of the so‐called peroxisomal docking/translocation
module, the transmembrane hydrophilic channel through which newly synthesized …
