The Arabidopsis ppi1 mutant is specifically defective in the expression, chloroplast import, and accumulation of photosynthetic proteins [PDF]

, 2003
The import of nucleus-encoded proteins into chloroplasts is mediated by translocon complexes in the envelope membranes. A component of the translocon in the outer envelope membrane, Toc34, is encoded in Arabidopsis by two homologous genes, atTOC33 and ...

GRKs and arrestins: Nomenclature and functions in GPCR‐dependent and ‐independent signalling

British Journal of Pharmacology, Volume 183, Issue 11, Page 2619-2633, June 2026.
G protein‐coupled receptor (GPCR) kinases (GRKs) and arrestins play a critical role in the regulation of GPCR signalling. Historic names of mammalian GRKs were replaced by systematic ones in the 1990s; however, both kinds of names are currently in use for mammalian arrestins.

The identification and purification of the heterotrimeric GTP-binding protein from squid (Loligo forbesi) photoreceptors [PDF]

Biochemical Journal, 1991
The principal GTP-binding protein (G-protein) from squid (Loligo forbesi) photoreceptor membranes has been identified by amino acid sequencing. The heterotrimeric protein was purified by detergent solubilization and ion-exchange chromatography. The amino acid sequence of the G-protein alpha-subunit (G-alpha) indicates that this subunit is closely ...

Frizzled Proteins are bona fide G Protein-Coupled Receptors [PDF]

, 2009
Receptors of the Frizzled family initiate Wnt ligand-dependent signaling controlling multiple steps in organism development and highly conserved in evolution. Misactivation of the Wnt/Frizzled signaling is cancerogenic.

A supramolecular assembly of cone‐specific G‐protein and cryptochrome 4a on lipid bilayer

The FEBS Journal, Volume 293, Issue 11, Page 3362-3375, June 2026.
Immobilized phospholipid bilayers on a sensor chip surface serve as membrane platform to investigate critical protein–lipid and protein–protein interaction processes by surface plasmon resonance. The putative magnetoreceptor cryptochrome 4a and the myristoylated cone‐specific G‐protein α‐subunit (Gtα) bind with high affinity to immobilized lipid ...

Phase specific association of heterotrimeric GTP-binding proteins with the actin-based cytoskeleton during thrombin receptor-mediated platelet activation [PDF]

, 1996
Subcellular distribution of heterotrimeric GTP-binding proteins during thrombin receptor-mediated platelet activation was examined, revealing two phases of translocation to the cytoskeleton.

Luteinizing hormone receptor knockout mouse: What has it taught us?

Andrology, Volume 14, Issue 4, Page 1017-1028, May 2026.
Abstract Luteinizing hormone (LH), along with its agonist choriongonadotropin (hCG) in humans, is the key hormone responsible for the tropic regulation of the gonadal function. LH and hCG act through their cognate receptor, the luteinizing hormone/choriongonadotropin receptor (LHCGR; more appropriately LHR in rodents lacking CG), located in the testis ...

Feedback control of excitability and high K+ induced epileptiform bursts in male rat hippocampal slices with a photocaged adenosine A1 receptor agonist

British Journal of Pharmacology, Volume 183, Issue 10, Page 2578-2591, May 2026.
Background and Purpose Adenosine is a potent regulator of neurotransmission and neuronal excitability, through activation of Gi coupled adenosine A1 receptors (A1Rs). Adenosine has gained interest as an anticonvulsant because of its endogenous involvement in ending seizure activity, but peripheral side effects require local application.

The Association of Heterotrimeric Gtp-Binding Protein (Go) with Microtubules

, 2008
The heterotrimeric GTP-binding regulatory proteins (G proteins) play an important role in the regulation of membrane signal transduction. Recently, we identified the association of Go protein with mitotic spindles.

Purification and characterization of heterologously produced cannabinoid receptor 1 and G proteins [PDF]

, 2007
G protein coupled receptors form the largest group of transmembrane proteins, which are involved in signal transduction and are targeted directly or indirectly by 40-50% of the drugs in the market.
