ARRDC4

ARRDC4 is known to interact with several proteins and participate in various protein-protein interaction networks. It has been reported to interact with G protein-coupled receptors (GPCRs), components of the endocytic machinery, and signaling molecules involved in receptor internalization and trafficking.

Yes, ARRDC4 can undergo post-translational modifications such as phosphorylation, ubiquitination, and acetylation. These modifications can regulate its stability, activity, and protein-protein interactions.

As of now, there are no known drugs specifically targeting ARRDC4. However, ongoing research or drug discovery efforts may identify compounds that can modulate its function or interactions in the future.

There is evidence to suggest that the expression of ARRDC4 can be altered during disease progression or under pathological conditions. For example, aberrant expression of ARRDC4 has been observed in certain cancers and cardiovascular diseases, indicating its potential role in disease pathogenesis.

ARRDC4 expression and activity can be regulated by specific stimuli or signaling pathways. For example, phosphorylation events mediated by protein kinases can modulate its function and localization in response to specific stimuli.

Yes, accumulating evidence suggests that ARRDC4 may play a role in certain human diseases or disorders. Studies have implicated its involvement in the pathogenesis of cancers, cardiovascular diseases, neurological disorders, and autoimmune conditions.

ARRDC4 can be found in multiple cellular compartments depending on the context. It has been observed in the cell membrane, endosomes, lysosomes, and cytoplasm. Its subcellular localization can vary based on the specific cellular processes it is involved in.

ARRDC4 is expressed in various tissues and cell types. mRNA expression profiling and immunohistochemistry studies have shown its presence in the brain, heart, liver, kidney, and immune cells.

Yes, ARRDC4 can modulate intracellular signaling pathways, particularly those involving GPCRs. It has been shown to regulate receptor internalization, desensitization, and recycling, thereby influencing downstream signaling events.

The presence of genetic variants or mutations in ARRDC4 associated with diseases has not been extensively explored. Genetic association studies or sequencing analyses may reveal any potential links between ARRDC4 genetic variations and disease susceptibility or progression.

The involvement of ARRDC4 in embryonic development or tissue homeostasis is not well-characterized. Investigating its expression patterns and conducting functional studies in relevant models can provide insights into its potential roles during development and in maintaining tissue equilibrium.

Currently, the diagnostic or prognostic utility of ARRDC4 as a biomarker is not well-established. However, further investigations exploring its expression patterns and associations with disease parameters may elucidate its potential as a biomarker in specific conditions.
