PHYSICAL PROPERTIES
STRUCTURE
motifs/domains
  • N terminal half homolog to BTG1
  • a nuclear export signal (NES)
  • a C terminal region containing a sequence rich in proline and glutamine, necessary and sufficient to control its stability
  • HOMOLOGY
    interspecies homolog to murine Tob1
    intraspecies homolog to BTG1
    Homologene
    FAMILY
  • anti-proliferative TOB1/BTG family
  • APRO protein family
  • CATEGORY adaptor , regulatory , signaling
    SUBCELLULAR LOCALIZATION     intracellular
    intracellular,cytoplasm
    text nuclear localization important for regulation of its antiproliferative activity
    basic FUNCTION
  • controling negatively cell growth
  • may negatively regulate sex steroid hormone action in bone formation
  • play important roles in spermatogenesis, embryonic dorsoventral patterning, osteogenesis, T-cell activation, and learning and memory
  • act primarily as transcriptional repressors in several signaling pathways
  • implicated in transcription in the nucleus and cytoplasmic mRNA deadenylation and turnover
  • involved in the general mechanism of mRNA decay by mediating mRNA deadenylation through interaction with CNOT8 and a general RNA-binding protein, PABPC1
  • mediates the recruitment of CNOT8 to the target of CPEB3 and elicits deadenylation and decay of the mRNA
  • CELLULAR PROCESS cell life, proliferation/growth
