PTPσ Antibody (SS-8): sc-100419

PTPσ Antibody (SS-8) is a mouse monoclonal IgG2b kappa light chain antibody that detects PTPσ protein of human origin by western blotting (WB), immunoprecipitation (IP), and enzyme-linked immunosorbent assay (ELISA). Anti-PTPσ antibody (SS-8) is available as the non-conjugated form. PTPσ is a receptor-type protein tyrosine phosphatase that plays a crucial role in various cellular processes, including cell signaling, development, and nerve repair. PTPσ is primarily located in the cell membrane, where PTPσ functions as a transmembrane protein, facilitating communication between the extracellular environment and intracellular signaling pathways. This localization allows PTPσ to interact with other membrane proteins and influence their phosphorylation status, thereby modulating cellular responses to external stimuli. PTPσ has been implicated in the regulation of insulin receptor signaling and may play a role in the repair mechanisms of adult nerves, highlighting PTPσ′s importance in both metabolic processes and neural regeneration. PTPσ′s structure includes an extracellular region, a single transmembrane segment, and two tandem intracytoplasmic catalytic domains, which are essential for enzymatic activity and interaction with other proteins. With four alternatively spliced transcript variants reported, PTPσ exhibits functional diversity that can impact various biological pathways, making anti-PTPσ antibody (SS-8) a valuable tool for researchers studying PTPσ′s role in health and disease.
