The thioredoxin‐like and one glutaredoxin domain are required to rescue the iron‐starvation phenotype of HeLa GLRX3 knock out cells

FEBS Letters, EarlyView.
Glutaredoxin (Grx) 3 proteins contain a thioredoxin domain and one to three class II Grx domains. These proteins play a crucial role in iron homeostasis in eukaryotic cells. In human Grx3, at least one of the two Grx domains, together with the thioredoxin domain, is essential for its function in iron metabolism.

P‐glycoprotein modulates the fluidity gradient of the plasma membrane of multidrug resistant CHO cells

FEBS Letters, EarlyView.
To explore the impact of the overexpression of the multidrug‐transporter P‐glycoprotein (ABCB1) on membrane fluidity, we compared the transversal gradient of mobility and microviscosity in plasma membranes of drug‐sensitive Chinese hamster ovary cells (AuxB1) and their multidrug‐resistant derivatives (B30) using the fluorescent n‐(9‐anthroyloxy) fatty ...

Expression and Purification of the Human Voltage-Gated Proton Channel (hHv1)

Bio-Protocol
The voltage-gated proton channel (Hv1) is a membrane protein that dissipates acute cell proton accumulations. To understand the molecular mechanisms explaining Hv1 function, methods for purifying the protein are needed. Previously, methods were developed

CREPT is required for murine stem cell maintenance during intestinal regeneration

Nature Communications, 2021
The role of CREPT, a recently identified tumor-promoting gene, outside of tumors is unclear. Here, the authors identify CREPT as maintaining murine intestinal stem cells, with embryonic deletion causing impaired cell proliferation and regeneration.

Functional consequences of the oligomeric assembly of proteorhodopsin. [PDF]

, 2015
The plasma membrane is the crucial interface between the cell and its exterior, packed with embedded proteins experiencing simultaneous protein-protein and protein-membrane interactions.

Evolutionary interplay between viruses and R‐loops

FEBS Letters, EarlyView.
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

CD146 is required for VEGF-C-induced lymphatic sprouting during lymphangiogenesis

Scientific Reports, 2017
VEGF-C is essential for lymphangiogenesis during development and tumor progression. VEGFR-3 is the well-known cognate receptor of VEGF-C to regulate lymphatic migration and proliferation, but the receptor of VEGF-C in regulating lymphatic sprouting, the ...

Direct Binding between Pre-S1 and TRP-like Domains in TRPP Channels Mediates Gating and Functional Regulation by PIP2

Cell Reports, 2018
Summary: Transient receptor potential (TRP) channels are regulated by diverse stimuli comprising thermal, chemical, and mechanical modalities. They are also commonly regulated by phosphatidylinositol-4,5-bisphosphate (PIP2), with underlying mechanisms ...

High-throughput isolation and characterization of untagged membrane protein complexes: outer membrane complexes of Desulfovibrio vulgaris. [PDF]

, 2012
Cell membranes represent the "front line" of cellular defense and the interface between a cell and its environment. To determine the range of proteins and protein complexes that are present in the cell membranes of a target organism, we have utilized a ...

Rotational Diffusion of Membrane Proteins: Characterization of Protein-Protein Interactions in Membranes [PDF]

Biophysical Journal, 2012
It has long been appreciated that the rotational diffusion coefficient (Dr) and hence the rotational correlation time (τr) of a transmembrane protein about its membrane normal axis is predicted to be highly sensitive to its cylindrical radius (e.g., Saffman and Delbruck (1)). Due to the highly viscous nature of a cellular membrane or a membrane bilayer,
