ARRDC3 known as Arrestin Domain Containing 3 is a relatively small protein with a mass of about 47 kDa. It acts by regulating the internalization and degradation of specific seven-transmembrane receptors through endosomal pathways. ARRDC3 expresses widely in various tissues with higher expressions in the brain heart and skeletal muscle. The protein contains an arrestin domain and initiates interactions with other proteins in cellular signaling.
Biological function summary
ARRDC3 influences cellular communication and adapts cellular responses. As part of a complex that includes members of the NEDD4 family E3 ligases it influences ubiquitination processes. ARRDC3 modulates the degradation and downregulation of G-protein-coupled receptors (GPCRs) which plays an important role in maintaining cellular signaling dynamics. This regulation affects multiple cellular functions including receptor recycling and signal transduction efficiency.
Pathways
ARRDC3 prominently integrates into the ubiquitin-proteasome system and GPCR signaling pathways. It functions in pathways that manage receptor trafficking and desensitization. The protein interacts closely with β-arrestins which play significant roles in GPCR internalization. The coordination with these proteins ensures the proper signaling cascade and termination impacting overall pathway efficiency.
Alterations in ARRDC3 expression have implications for cancer and obesity. In certain cancers such as breast cancer altered ARRDC3 levels correlate with tumor progression and metastasis. The protein also associates with energy balance and body weight regulation linking its function to obesity. The interaction with β-arrestins in these disorders suggests a mechanism where disrupted receptor trafficking exacerbates these conditions.
