Prf1, Recombinant, Rat, aa25-554, His-Tag (Perforin-1)

Plays a key role in secretory granule-dependent cell death, and in defense against virus-infected or neoplastic cells. Can insert into the membrane of target cells in its calcium-bound form, oligomerize and form large pores. Promotes cytolysis and apoptosis of target cells by facilitating the uptake of cytotoxic granzymes. Source: Recombinant protein corresponding to aa25-554 from rat Prf1, fused to His-Tag at N-terminal, expressed in E. coli.
