Computational model explains high activity and rapid cycling of Rho GTPases within protein complexes. [PDF]
PLoS Computational Biology, 2006 Formation of multiprotein complexes on cellular membranes is critically dependent on the cyclic activation of small GTPases. FRAP-based analyses demonstrate that within protein complexes, some small GTPases cycle nearly three orders of magnitude faster ...

Dependence of protein-induced lipid bilayer deformations on protein shape [PDF]
, 2022 Membrane proteins typically deform the surrounding lipid bilayer membrane, which can play an important role in the function, regulation, and organization of membrane proteins. Membrane elasticity theory provides a beautiful description of protein-induced lipid bilayer deformations, in which all physical parameters can be directly determined from ...

Binding of anisotropic curvature-inducing proteins onto membrane tubes [PDF]
Soft Matter 18, 3384-3394 (2022), 2022 Bin/Amphiphysin/Rvs superfamily proteins and other curvature-inducing proteins have anisotropic shapes and anisotropically bend biomembrane. Here, we report how the anisotropic proteins bind the membrane tube and are orientationally ordered using mean-field theory including an orientation-dependent excluded volume.

Structural and mechanistic insights into regulation of the retromer coat by TBC1d5
Nature Communications, 2016 Retromer is recruited to endosomes by the small GTPase Rab7 and sorting nexin 3. Here, the authors report the interaction between a GTPase-activating protein TBC1d5 and Rab7, examine the biochemical details of the interaction with retromer, and discuss ...

A serine/threonine protein kinase encoding gene KERNEL NUMBER PER ROW6 regulates maize grain yield
Nature Communications, 2020 Selection of kernel number per ear has improved maize yield, but the genetic base is unclear. Here, the authors reveal that a serine/threonine protein kinase KNR6 is a positive regulator of the trait and show in vitro evidences that KNR6 may function ...

Curvature sensing of curvature-inducing proteins with internal structure [PDF]
Phys. Rev. E 109, 024403 (2024), 2023 Many types of peripheral and transmembrane proteins can sense and generate membrane curvature. Laterally isotropic proteins and crescent proteins with twofold rotational symmetry, such as Bin/Amphiphysin/Rvs superfamily proteins, have been studied theoretically. However, proteins often have an asymmetric structure or a higher rotational symmetry.

Critical appraisal on mitochondrial dysfunction in Alzheimer’s disease
AGING MEDICINE, Volume 5, Issue 4, Page 272-280, December 2022., 2022 Amyloid plaques deposit on neurons in case of Alzheimer's Disease. Mitochondria play a vital role in pathogenesis of Alzheimer's Disease. Mitochondrial dysfunction can lead to formation of mPTP, alteration of complexes 1,3 and 4, deficits in bioenergetics with impaired mitochondrial biogenesis. Abstract It is widely recognized that Alzheimer's disease (
