    basic FUNCTION
  • insuline-like growth factor binding protein 7 (related protein 1)
  • prostacyclin stimulating factor tumor derived adhesion factor
  • inducing senescence and apoptosis through autocrine/paracrine pathways
  • stimulating BNIP3L transcription, at least in part, by increasing intracellular levels of SMARCB1, leading to formation of a SMARCB1-containing SWI/SNF chromatin-remodeling complex, recruited to the BNIP3L promoter and facilitates BNIP3L transcriptional activation
  • factor required for an activated BRAF oncogene to induce senescence or apoptosis in primary human cells (Wajapeyee 2009)
  • functions mostly independent of the IGF signaling pathway and acts as a tumor suppressor in multiple cancers (Huang 2010)
  • can modulate the stimulatory effect of VEGF on angiogenesis by interfering with VEGF expression as well as VEGF signaling and not by inducing apoptosis (Tamura 2009)
  • dispensable for BRAF(V600E)-induced senescence in human melanocytes (Scurr 2010)
  • involved in several cellular processes, including proliferation, senescence and apoptosis (Vizioli 2010)
  • CELLULAR PROCESS cell life, proliferation/growth
