Polyclonal antibody produced in rabbits immunizing with a synthetic peptide corresponding to N-terminal residues of human BTG1(B-cell translocation gene 1 protein)
BTG1(B-cell translocation gene 1 protein) is an anti-proliferative protein. Its expression is associated with the early G1 phase of the cell cycle. A chromosomal aberration involving BTG1 may be a cause of a form of B-cell chronic lymphocytic leukemia. BTG1 expression is maximal in the G0/G1 phases of the cell cycle and downregulated when cells progressed through G1. GTG1 negatively regulates cell proliferation. BTG1 is a novel important coactivator involved in the regulation of myoblast differentiation. BTG1 may play an important role in the process of angiogenesis. Antiproliferative proteins of the BTG/Tob family are degraded by the ubiquitin-proteasome system. The C-terminal regions are necessary and sufficient to control the stabilities of BTG1, BTG2, Tob, and Tob2 proteins.
