ASB8 Human

The ASB8 protein is characterized by the presence of ankyrin repeats and a SOCS box. Ankyrin repeats are known for their role in protein-protein interactions, while the SOCS box is involved in protein degradation. The SOCS box proteins, including ASB8, act as a bridge between substrate proteins and E3 ubiquitin-protein ligases, facilitating the ubiquitination and subsequent proteasomal degradation of target proteins .

ASB8 is expressed in various tissues, with the highest expression observed in skeletal muscle. Other tissues with notable expression levels include the heart, brain, placenta, liver, kidney, and pancreas. The protein is predominantly localized in the cytoplasm .

ASB8 is involved in several biological pathways, including:

• Class I MHC mediated antigen processing and presentation
• Metabolism of proteins

These pathways highlight the importance of ASB8 in immune response and protein metabolism .

Research has shown that ASB8 may be a substrate-recognition component of a SCF-like ECS (Elongin-Cullin-SOCS-box protein) E3 ubiquitin-protein ligase complex. This complex mediates the ubiquitination and degradation of target proteins, which is crucial for maintaining cellular homeostasis .

The study of ASB8 and its recombinant forms can provide insights into its role in various diseases and potential therapeutic applications. For instance, understanding the mechanisms of ASB8-mediated protein degradation can aid in the development of treatments for conditions associated with protein aggregation and degradation.
