– 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 (Yeast, His) is expressed in yeast with N-6xHis tag. The predicted molecular weight is 26.2 kDa and the accession number is O00481.
