- Extra Details:
- Interleukin 4 induced protein 1(IL4I1), also known as protein FIG1 and L amino acid oxidase, is encoded by a B cell IL4 inducible gene, FIG1, and is highly expressed in primary metastinal B cell lymphomas (14). It belongs to the flavin monoamine oxidase family, FIG1 subfamily. Enzymological characterization reveals that IL4I1 has L amino acid oxidase activity with preference toward aromatic amino acids. Studies have shown that hI L4I1 inhibited the proliferation of CD3 stimulated T lymphocytes with a similar effect on CD4(+) and CD8(+) T cells (5) . Its inhibitory effect was dependent on enzymatic activity and H2O2 production. Its restricted expression to l ymphoid tissues indicates that it may play an important function in the immune system (1, 4).
