[HTML][HTML] Novel structural approaches to study GPCR regulation

MA Alfonzo-Méndez, R Alcántara-Hernández… - International Journal of …, 2016 - mdpi.com
Background: Upon natural agonist or pharmacological stimulation, G protein-coupled receptors
(GPCRs) are subjected to posttranslational modifications, such as phosphorylation and …

[HTML][HTML] α1B-Adrenergic Receptors Differentially Associate with Rab Proteins during Homologous and Heterologous Desensitization

…, OB Sánchez-Reyes, MA Alfonzo-Méndez… - PloS one, 2015 - journals.plos.org
Internalization of G protein-coupled receptors can be triggered by agonists or by other
stimuli. The process begins within seconds of cell activation and contributes to receptor …

[HTML][HTML] Dual clathrin and integrin signaling systems regulate growth factor receptor activation

MA Alfonzo-Méndez, KA Sochacki, MP Strub… - Nature …, 2022 - nature.com
The crosstalk between growth factor and adhesion receptors is key for cell growth and
migration. In pathological settings, these receptors are drivers of cancer. Yet, how growth and …

Human α 1D -adrenoceptors (α 1D -ARs) are a group of the seven transmembrane-spanning
proteins that mediate many of the physiological and pathophysiological actions of …

Protein kinase C activation promotes α1B-adrenoceptor internalization and late endosome trafficking through Rab9 interaction. Role in heterologous desensitization

MA Alfonzo-Méndez, DA Hernández-Espinosa… - Molecular …, 2017 - ASPET
Upon agonist stimulation, α 1B -adrenergic receptors couple to G q proteins, calcium
signaling and protein kinase C activation; subsequently, the receptors are phosphorylated, …
