B细胞迁移基因2抗体说明书

BTG2 is a member of the BTG/Tob family. This family has structurally related proteins that appear to have antiproliferative properties. BTG2 is involved in the regulation of the G1/S transition of the cell cycle. It modulates transcription regulation mediated by ESR1(referenced from Entrez Gene). BTG2 expression is induced in vivo during neurogenesis, and the gene is transiently expressed in vitro in rat pheochromocytoma PC12 cells after induction of neuronal differentiation by addition of nerve growth factor (NGF); suggesting that BTG2 is functionally significant during the neuronal differentiation process (PMID: 12360398).
Function : Anti-proliferative protein; the function is mediated by association with deadenylase subunits of the CCR4-NOT complex. Activates mRNA deadenyltion in a CNOT6 and CNOT7-dependent manner. In vitro can inhibit deadenylase activity of CNOT7 and CNOT8. Involved in cell cycle regulation. Could be involved in the growth arrest and differentiation of the neuronal precursors. Modulates transcription regulation mediated by ESR1. Involved in mitochondrial depolarization and neurite outgrowth.
Subunit : Interacts with PRKCABP. Interacts with CNOT7 and CNOT8; indicative for an asscociation with the CCR4-NOT complex. Interacts with PIN1, inducing mitochondrial depolarization.
Post-translational modifications : Phosphorylated at Ser-147 by MAPK1/ERK2 and MAPK3/ERK1, and at Ser-149 by MAPK14, leading to PIN1-binding and mitochondrial depolarization.
Similarity : Belongs to the BTG family.
