In biology, the word gene (from , ; "...Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a ba ...
.
Often put together with and studied alongside TGFB1I1 is the mouse homologue HIC-5 ( Hydrogen Peroxide-Inducible Clone-5). As the name suggests, TGFB1I1 is an induced form of the larger family of
TGBF1. Studies suggest TGBF1I1 plays a role in processes of cell growth, proliferation,
migration, differentiation
and senescence.
TGBF1I1 is most localized at focal adhesion complexes of cells,
although it may be found active in the cytosol, nucleus and cell membrane as well.
Functions
Transforming growth factor beta-1-induced transcript 1 plays a role in a number of cell functions. Originally, TGFB1I1 was isolated as a senescence-inducing gene from mouse osteoblastic cells through treatment with transforming growth factor beta-1 and hydrogen peroxide.
During this, TGFB1I1 was also being independently discovered by numerous other groups and was characterized as a focal adhesion protein, an androgen and glucocorticoid receptor co-activator,
a negative regulator of muscle differentiation,
and major player in the recovery of arterial media.
