Cryomicroscopy reveals the structural basis for a flexible hinge motion in the immunoglobulin M pentamer

Nature Communications, 2022
Immunoglobulin M (IgM) is the Ig isotype that serves as the first line of host defence during infection. Here, the authors image the full-length IgM pentamer by cryo-EM, revealing the structure and hinge motion of the antigen binding domains.

Loss of RASGRP1 in humans impairs T‐cell expansion leading to Epstein‐Barr virus susceptibility

EMBO Molecular Medicine, 2018
Inherited CTPS1, CD27, and CD70 deficiencies in humans have revealed key factors of T‐lymphocyte expansion, a critical prerequisite for an efficient immunity to Epstein–Barr virus (EBV) infection.

Differential roles for the adapters Gads and LAT in platelet activation by GPVI and CLEC-2 [PDF]

, 2008
Background: The adapter proteins SLP-76 and LAT have been shown to play critical roles in the activation of PLCc2 in platelets downstream of GPVI/FcRc and the C-type lectin receptor CLEC-2.

Dinuclear PhosphoiminoBINOL-Pd Container for Malononitrile: Catalytic Asymmetric Double Mannich Reaction for Chiral 1,3-Diamine Synthesis

Scientific Reports, 2018
A phosphoiminoBINOL ligand was designed to form a dinuclear metal complex that could hold a malononitrile molecule. The dinuclear bis(phosphoimino)binaphthoxy-Pd2(OAc)2 complex catalyzed a double Mannich reaction of N-Boc-imines with malononitrile to ...

Retrograde and Anterograde Transport of Lat-Vesicles during the Immunological Synapse Formation: Defining the Finely-Tuned Mechanism

Cells, 2021
LAT is an important player of the signaling cascade induced by TCR activation. This adapter molecule is present at the plasma membrane of T lymphocytes and more abundantly in intracellular compartments.

Interrogating ligand-receptor interactions using highly sensitive cellular biosensors

Nature Communications, 2023
Interactions of membrane-resident proteins are important targets for therapeutic interventions but most methods to study them are either costly, laborious or fail to reflect the physiologic interaction of membrane resident proteins in trans.

Deep evolutionary conservation of an intramolecular protein kinase activation mechanism [PDF]

, 2012
DYRK-family kinases employ an intramolecular mechanism to autophosphorylate a critical tyrosine residue in the activation loop. Once phosphorylated, DYRKs lose tyrosine kinase activity and function as serine/threonine kinases.

B cells extract antigens at Arp2/3-generated actin foci interspersed with linear filaments

eLife, 2019
Antibody production depends on B cell internalization and presentation of antigens to helper T cells. To acquire antigens displayed by antigen-presenting cells, B cells form immune synapses and extract antigens by the mechanical activity of the acto ...
