Anti-UBXN1 / UBX domain-containing protein 1

Adding 0.2 ml of distilled water will yield a concentration of 500 ug/ml. UBXN1 antibody targets UBX domain-containing protein 1, encoded by the UBXN1 gene. UBXN1 is a cytoplasmic and endoplasmic reticulum-associated protein that belongs to the UBX domain protein family, a group of cofactors that interact with the AAA ATPase VCP, also known as p97. Through its UBX domain, UBXN1 participates in protein quality control pathways by linking VCP to specific substrates and adaptor complexes. This positioning allows UBXN1 to influence the fate of misfolded, ubiquitinated, or regulatory proteins within the cell.Functionally, UBX domain-containing protein 1 is involved in ubiquitin-dependent processes that regulate protein turnover and cellular homeostasis. UBXN1 has been shown to modulate endoplasmic reticulum-associated degradation, a pathway responsible for identifying and removing misfolded proteins from the ER. By coordinating with VCP and other ubiquitin pathway components, UBXN1 helps ensure efficient extraction and downstream handling of these substrates. A UBXN1 antibody supports studies focused on protein degradation pathways and ubiquitin-mediated regulation.Beyond ER stress responses, UBXN1 also contributes to broader aspects of proteostasis and signaling. It has been implicated in the regulation of inflammatory signaling pathways, where it can influence the stability or activity of signaling intermediates. Through these interactions, UBXN1 acts as a regulatory scaffold rather than an enzymatic factor, fine-tuning cellular responses to stress and signaling cues. These roles place UBXN1 at the intersection of protein quality control and signal transduction.UBXN1 is expressed in multiple tissues and cell types, reflecting the universal need for regulated protein turnover. Its cellular localization can vary depending on context, with enrichment in cytoplasmic compartments associated with the ER and protein degradation machinery. UBXN1 can associate with additional cofactors beyond VCP, suggesting that it participates in dynamic multiprotein complexes that adapt to changing cellular conditions.From a disease-relevance perspective, dysregulation of ubiquitin-proteasome and ERAD pathways is linked to neurodegenerative disorders, inflammatory diseases, and cancer. Because UBXN1 modulates these pathways indirectly through adaptor functions, it has attracted interest as a regulatory node rather than a core degradation enzyme. Altered UBXN1 expression or function may influence how cells cope with proteotoxic stress, making it a relevant target for mechanistic studies of disease-associated protein homeostasis.At the molecular level, UBX domain-containing protein 1 contains a conserved UBX domain that mediates interaction with VCP, along with additional regions that contribute to substrate and adaptor binding. Post-translational modifications and complex assembly state can influence UBXN1 activity and its apparent behavior in biochemical assays without implying changes to the primary amino acid sequence. A UBXN1 antibody is suitable for research applications aimed at investigating protein quality control, ubiquitin-dependent pathways, and stress-responsive cellular mechanisms, with NSJ Bioreagents providing reagents intended for research use.
