Mutagenesis and activity assays in vitro and in vivo identify residues in the tethered agonist of GPR116, as well as those within the extracellular loops, that are critical for mediating the response to the tethered agonist.

The membrane proteins Reck and Gpr124 are integral components of a novel Wnt7a/Wnt7b-specific signaling complex, and there is a distinctive requirement for Wnt/β-catenin signaling in tip cells during angiogenesis in the central nervous system.
An integrative structural and biophysical workflow indicates engagement of VRC01 germline antibodies can occur with a gp120 426c core construct containing all wild-type N-linked glycosylation sites, including the Asn276 glycan.

The orphan receptor GPR158 is highly regulated by stress exposure and acts on key neuronal signaling pathways in the prefrontal cortex to control depressive-like behaviors.
A cryo-EM structure of TMEM87A unexpectedly reveals it is structurally related to seven other proteins including Wntless, a chaperone for lipidated and secreted Wnt morphogens, suggesting GOLD-domain seven-transmembrane helix (GOST) proteins may all similarly traffic membrane-associated cargo.
The PPARγ protein acts in macrophages to inhibit breast cancer progression and mediate the anti-tumor effects of rosiglitazone by suppressing Gpr132 – a pro-tumor and pro-inflammatory factor in macrophages.

ESRP1 is central to intestinal barrier integrity in mice and humans and alterations in ESRP1 function or expression contribute to intestinal pathology, partly through modified expression of ESRP1-specific GPR137 isoforms.

Signal-peptide cleavage of HIV-1 envelope glycoprotein is delayed because of alpha-helical structure covering the cleavage site, effecting early cleavage alters the folding pathway and resulting in localized misfolding and reduced viral fitness.
Lymph node gp120 specific B cells extract locally injected HIV-1 gp120 from SIGN-R1 positive macrophages that line the subcapsular sinus overlying the lymph node interfollicular channels.
The survival of Drosophila amacrine neurons is controlled by neurotrophic signaling mediated by interactions between the cell surface protein DIP-γ and its partner Dpr11, which is expressed on presynaptic photoreceptors.
