SQSTM1 Antibodies

SQSTM1 antibodies are developed to specifically target the Sequestosome 1 (SQSTM1) protein, also known as p62. SQSTM1 is a multifunctional adaptor protein that plays a critical role in autophagy, the ubiquitin-proteasome system, and cellular signaling. It acts as a scaffold for protein-protein interactions, facilitating the degradation of ubiquitinated proteins through autophagy. 

Content

SQSTM1 (p62) is involved in several key cellular processes. It serves as an adaptor that links ubiquitinated proteins to autophagosomes for degradation, playing a pivotal role in maintaining cellular homeostasis. SQSTM1 also acts in cellular signaling pathways, including NF-κB activation, oxidative stress response, and mTOR signaling. Dysregulation of SQSTM1 can lead to protein aggregation, impaired autophagy, and abnormal cellular signaling, which are implicated in neurodegenerative diseases like Alzheimer’s and Parkinson’s disease, as well as cancers.

Application

SQSTM1 antibodies are widely applied in research techniques, including:

• Immunohistochemistry (IHC): Employed to visualize the localization of SQSTM1 in tissue sections, revealing its distribution in various cell types. IHC is essential for studying SQSTM1’s role in disease contexts, such as cancer and neurodegeneration, by highlighting protein accumulations and aggregates.
• Immunofluorescence (IF): Enables the detailed observation of SQSTM1 at the cellular level, providing insights into its subcellular localization, aggregation, and co-localization with autophagosomes and other cellular structures. IF is crucial for studying the dynamics of autophagy and protein degradation.
• Enzyme-Linked Immunosorbent Assay (ELISA): Used for quantifying SQSTM1 protein levels in various biological samples, including serum and cell culture media. ELISA assays are valuable for biomarker research and studying the effects of therapeutic interventions targeting autophagy pathways.

These applications make SQSTM1 antibodies crucial tools for advancing research on autophagy, protein homeostasis, and cellular signaling. They contribute to understanding the molecular mechanisms underlying various diseases, including neurodegenerative disorders and cancers, and aid in developing potential therapeutic strategies targeting SQSTM1-mediated pathways.
