Protein attributes

Sequence length	156 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	Produced by lymphocytes activated by specific antigens or mitogens. IFN-gamma, in addition to having antiviral activity, has important immunoregulatory functions. It is a potent activator of macrophages, it has antiproliferative effects on transformed cells and it can potentiate the antiviral and antitumor effects of the type I interferons.
Subunit structure	Homodimer.
Subcellular location	Secreted.
Tissue specificity	Released primarily from activated T lymphocytes.
Sequence similarities	Belongs to the type II (or gamma) interferon family.
