The PUBCHEM_BIOASSAY assay is designed to identify small molecule antagonists that can bind to Siah-1 and a peptide ligand through fluorescence polarization. Its category is confirmatory and it specifically targets a single protein. This assay is related to other pubchem assays such as AID1826, AID2127, and AID2141, which are defined by the depositor. The organism used for the assay is Homo sapiens and its description falls under the category of binding. Does this molecule exhibit efficacy in this assay?
