– Plays a role in T-cell activation and in the adaptive immune response. Regulates the proliferation of activated T-cells. Regulates the release of cytokines and IFNG by activated T-cells. Mediates the response of T-cells toward infected and transformed cells that are characterized by high levels of phosphorylated metabolites, such as isopentenyl pyrophosphate. BTN3A1 Protein, Human, Recombinant (E. coli, His) is expressed in E. coli expression system with N-10xHis tag. The predicted molecular weight is 30.2 kDa and the accession number is O00481.
