Membrane Remodeling: Passive Crosslinkers Drive Membrane Tubulation.

Summary of "Membrane Remodeling: Passive Crosslinkers Drive Membrane Tubulation."

A new study has uncovered three mechanisms of motor-independent membrane tubulation. In vitro reconstitution using a minimal set of proteins shows that the accumulation of crosslinking proteins at the membrane-microtubule interface is sufficient to drive tubulation, which is enhanced by coupling with microtubule dynamics.

Mechanisms of Motor-Independent Membrane Remodeling Driven by Dynamic Microtubules.

Microtubule-dependent organization of membranous organelles occurs through motor-based pulling and by coupling microtubule dynamics to membrane remodeling. For example, tubules of endoplasmic reticulu...

Nanoparticles binding to lipid membranes: from vesicle-based gels to vesicle tubulation and destruction.

While cells offer numerous inspiring examples in which membrane morphology and function are controlled by interactions with viruses or proteins, we still lack design principles for controlling membran...

Zika NS1-induced ER remodeling is essential for viral replication.

Zika virus (ZIKV), a recently emerged member of the flavivirus family, forms replication compartments at the ER during its lifecycle. The proteins that are responsible for the biogenesis of replicatio...

Medical and Biotech [MESH] Definitions

The voltage difference, normally maintained at approximately -180mV, across the INNER MITOCHONDRIAL MEMBRANE, by a net movement of positive charge across the membrane. It is a major component of the PROTON MOTIVE FORCE in MITOCHONDRIA used to drive the synthesis of ATP.

The passive movement of molecules exceeding the rate expected by simple diffusion. No energy is expended in the process. It is achieved by the introduction of passively diffusing molecules to an enviroment or path that is more favorable to the movement of those molecules. Examples of facilitated diffusion are passive transport of hydrophilic substances across a lipid membrane through hydrophilic pores that traverse the membrane, and the sliding of a DNA BINDING PROTEIN along a strand of DNA.

A large multisubunit protein complex that is found in the THYLAKOID MEMBRANE. It uses light energy derived from LIGHT-HARVESTING PROTEIN COMPLEXES to drive electron transfer reactions that result in either the reduction of NADP to NADPH or the transport of PROTONS across the membrane.

A family of monosaccharide transport proteins characterized by 12 membrane spanning helices. They facilitate passive diffusion of GLUCOSE across the CELL MEMBRANE.

A member of the vesicle-associated membrane protein family involved in the MEMBRANE FUSION of TRANSPORT VESICLES to their target membrane.
