Transmembrane domain dependent inhibitory function of FcγRIIB

open access: yesProtein & Cell, 2018
FcγRIIB, the only inhibitory IgG Fc receptor, functions to suppress the hyper-activation of immune cells. Numerous studies have illustrated its inhibitory function through the ITIM motif in the cytoplasmic tail of FcγRIIB. However, later studies revealed

Structural determinants of PINK1 topology and dual subcellular distribution

open access: yesBMC Cell Biology, 2010
Background PINK1 is a mitochondria-targeted kinase that constitutively localizes to both the mitochondria and the cytosol. The mechanism of how PINK1 achieves cytosolic localization following mitochondrial processing remains unknown.

The CD28 Transmembrane Domain Contains an Essential Dimerization Motif

open access: yesFrontiers in Immunology, 2020
CD28 plays a critical role in regulating immune responses both by enhancing effector T cell activation and differentiation and controlling the development and function of regulatory T cells.

Interhelical H-Bonds Modulate the Activity of a Polytopic Transmembrane Kinase

open access: yesBiomolecules, 2021
DesK is a Histidine Kinase that allows Bacillus subtilis to maintain lipid homeostasis in response to changes in the environment. It is located in the membrane, and has five transmembrane helices and a cytoplasmic catalytic domain.

An allosteric Sec61 inhibitor traps nascent transmembrane helices at the lateral gate

open access: yeseLife, 2014
Membrane protein biogenesis requires the coordinated movement of hydrophobic transmembrane domains (TMD) from the cytosolic vestibule of the Sec61 channel into the lipid bilayer.

Calmodulin adopts an extended conformation when interacting with L-selectin in membranes. [PDF]

open access: yesPLoS ONE, 2013
Calmodulin, an intracellular calcium-binding protein, is thought to regulate ectodomain shedding of many membrane proteins, but the underlying molecular mechanism has remained unclear.

Hibiscus chlorotic ringspot virus p27 and Its Isoforms Affect Symptom Expression and Potentiate Virus Movement in Kenaf (Hibiscus cannabinus L.)

open access: yesMolecular Plant-Microbe Interactions, 2006
Hibiscus chlorotic ringspot virus (HCRSV), a member of the genus Carmovirus, encodes p27 (27-kDa protein) and two other in-frame isoforms (p25 and p22.5) that are coterminal at the carboxyl end.

NMR Detection and Structural Modeling of the Ethylene Receptor LeETR2 from Tomato

open access: yesMembranes, 2022
The gaseous plant hormone ethylene influences many physiological processes in plant growth and development. Plant ethylene responses are mediated by a family of ethylene receptors, in which the N-terminal transmembrane domains are responsible for ...
