HIP-55 Antibody (E-5): sc-398358

HIP-55 Antibody (E-5) is a mouse monoclonal IgG1 antibody that detects HIP-55 in mouse, rat, and human samples through applications such as western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA). HIP-55, also known as HPK1-interacting protein of 55 kDa, ABP1, SH3P7, or DBNL, is a 430 amino acid cytoplasmic protein that plays a crucial role in the immune response by acting as an actin-binding adapter protein. HIP-55 is essential for the formation and function of the immunological synapse, where HIP-55 regulates T-cell activation by linking T-cell receptors to the actin cytoskeleton, thereby facilitating gene activation and endocytic processes. The presence of an ADF-H domain and a SH3 domain in HIP-55 allows interaction with other proteins, including SHANK2, SHANK3, and PRAM-1, which are vital for maintaining synaptic integrity and signaling. Notably, HIP-55 is subject to degradation by caspases during apoptosis, highlighting HIP-55′s importance in cellular processes and the regulation of immune responses. With an ability to bind F-actin without participating in actin polymerization, capping, or bundling, HIP-55 serves as a key player in cell migration and neuronal plasticity, making anti-HIP-55 antibody (E-5) an invaluable tool for researchers studying these critical biological processes.
