ASNS antiboies are a key metabolic enzyme, mainly found in tissues such as the liver, pancreas and brain of vertebrates. This enzyme catalyzes the synthesis of aspartic acid and glutamine into asparagine, a process that is crucial for maintaining the amino acid balance within cells, supporting protein synthesis and the survival of tumor cells. Studies have shown that the expression level of ASNS is associated with chemotherapy resistance in certain cancers, making it a research target for tumor treatment.
