Technical Data
TOB2 (Protein Tob2, Transducer of erbB-2 2, Protein Tob4, KIAA1663, TOB4, TOBL, TROB2)
TOB2 is a 344aa rich novel member of the Tob:BTG1 anti-proliferative family of proteins characterized by similarities in their N-terminal BTG:Tob homology domains. This anti-proliferative protein inhibits cell cycle progression from the G0:G1 to S phases and is involved in cell cycle regulation through interaction with Caf1, a component of the CCR4 transcription factor complex that associates with cyclin-dependent kinases. Recent reports suggest that TOB2 plays important roles in spermatogenesis, embryonic dorsoventral patterning, osteogenesis, T-cell activation, learning and memory and acts primarily as a transcriptional repressor in several signaling pathways. TOB2, a signaling protein, may participate in transcriptional regulation of several genes. It is a regulatory protein ubiquitously expressed in most of the tissues.
