title: BTG2, its family and its tutor.
abstract: The human BTG2 gene is one of five members of a newly identified family of antiproliferative genes. BTG2 was first described as an immediate early gene whose expression is induced in response to mitogenic as well as differentiative and antiproliferative factors. More recently, we have shown that BTG2 expression is also induced in response to genotoxic stress through a p53-dependent mechanism. Experimental overexpression of the BTG2 gene in NIH3T3 and PC12 cells leads to a partial inhibition of cell proliferation. BTG2 protein physically interacts with Caf1 protein, an element of a general transcription complex, and with PRMT1, a protein-arginine N-methyl transferase. We speculate on the role of BTG2 as a modulator of the intracellular signal transduction cascade.
