Mitogenic properties of pokeweed lectin-D isoforms on human peripheral blood lymphocytes: non-mitogen PL-D1 and mitogen PL-D2.

We investigated native structures and mitogenic properties of pokeweed lectin-D isoforms (PL-D1 and -D2) on human peripheral blood lymphocytes along with other isolectins (PL-A to -C). Both native PL-D isoforms appeared to behave as monomers. PL-D2 proliferated the lymphocytes like PL-C, whereas PL-D1 had no mitogenicity. PL-D1 acquired mitogenic activity after trimming of the C-terminal dipeptide.
