Supplementary information

Beta-arrestin 2 also known as arrb2 or b-arrestin mechanically functions to regulate G protein-coupled receptor (GPCR) signaling. This protein has a molecular mass of approximately 47 kDa and is ubiquitously expressed across various tissues including the brain lungs and heart. Beta-arrestin 2 works by binding to phosphorylated GPCRs facilitating receptor desensitization and endocytosis which stops the receptor's signaling activity and mediates receptor internalization.
Biological function summary

Beta-arrestin 2 plays an important role in mediating signal transduction pathways beyond GPCR desensitization including those involved in cell communication and cellular response regulation. Beta-arrestin 2 interacts with multiple signaling proteins to form complexes that facilitate signaling pathways notably influencing MAPK (Mitogen-Activated Protein Kinase) pathways. It provides a scaffold for downstream signaling molecules affecting cell signaling outcomes.

Pathways

Beta-arrestin 2 significantly participates in two important biological pathways: the MAPK pathway and the Wnt signaling pathway. Through these pathways beta-arrestin 2 interacts with signaling proteins such as ERK1/2 (Extracellular signal-Regulated Kinases) and dishevelled proteins. These interactions highlight beta-arrestin 2's ability to modulate signal strength and duration contributing to diverse cellular responses.

Beta-arrestin 2 is implicated in conditions like heart failure and certain cancers. The aberrant regulation of beta-arrestin 2-related pathways can lead to uncontrolled cell proliferation or inadequate heart responses. Additionally beta-arrestin 2 is connected to proteins like GPCR kinases in the context of heart failure and MAPK proteins within oncogenic processes underlining its potential as a therapeutic target.
