G protein-coupled receptors (GPCRs) are the most structurally diverse family of signaling proteins and regulate a variety of cell function. For most GPCRs, the cell surface is their functional destination where they are able to respond a wide range of ...

Receptor crosstalk improves concentration sensing of multiple ligands [PDF]
Cells need to reliably sense external ligand concentrations to achieve various biological functions such as chemotaxis or signaling. The molecular recognition of ligands by surface receptors is degenerate in many systems leading to crosstalk between different receptors.

Expression of interleukin 2 receptors on activated human B cells. [PDF]
Using anti-Tac, a monoclonal anti-interleukin 2 (IL-2) receptor antibody, we have explored the possibility that certain activated B cells display receptors for IL-2.

The stochastic entry of enveloped viruses: Fusion vs. endocytosis [PDF]
Viral infection requires the binding of receptors on the target cell membrane to glycoproteins, or ``spikes,'' on the viral membrane. The initial entry is usually classified as fusogenic or endocytotic.

Guanylate Cyclase, a Cell Surface Receptor
Guanylate cyclase appears to represent a central member of a diverse family of proteins involved in cell signaling mechanisms including the protein kinases, a low Mr ANP receptor, and possibly adenylate cyclase (based on limited sequence identity with the yeast enzyme).

Characteristics of the Kelch domain containing (KLHDC) subfamily and relationships with diseases
The Kelch protein superfamily includes 63 members, with the KLHDC subfamily having 10 proteins. While their functions are not fully understood, recent advances in KLHDC2's structure and role in protein degradation have highlighted its potential for drug development, especially in PROTAC therapies.

Five layers of receptor signalling in γδ T cell differentiation and activation
The contributions of gamma-delta T cells to immunity to infection or tumours critically depend on their activation and differentiation into effectors capable of secreting cytokines and killing infected or transformed cells.

Accuracy of direct gradient sensing by cell-surface receptors [PDF]
Chemotactic cells of eukaryotic organisms are able to accurately sense shallow chemical concentration gradients using cell-surface receptors. This sensing ability is remarkable as cells must be able to spatially resolve small fractional differences in the numbers of particles randomly arriving at cell-surface receptors by diffusion.

Palmitoylation of the canine histamine H2 receptor occurs at Cys305 and is important for cell surface targeting [PDF]
To determine the presence and functional role of the histamine H2 receptor (H2R) palmitoylation, a receptor with a Cys305 to Ala (A305 receptor) mutation was generated. Wild-type (WT) and A305 receptors were tagged at their N-termini with a hemagglutinin

Insertion of the FeB cofactor in cNORs lacking metal inserting chaperones
Nitric oxide reductase is an enzyme found in the bacterial denitrification pathway. The NOR active site contains a non‐heme iron, often, but not always inserted with the assistance of chaperones. Here, we study the insertion of FeB in the subfamily of cNORs lacking chaperones and found a putative channel, conserved in the family, perhaps enabling the ...
