    basic FUNCTION
  • transcription factor that functions as a repressor for GATA-mediated transcription, androgen-repressible, apoptosis associated
  • repressing transcription of genes involved in chondrocyte differentiation
  • regulator of chondrocytes proliferation and survival through the control of STAT3 expression (Suemoto 2007)
  • plays a pivotal role downstream of GDF5 signaling in promoting chondrogenesis and apoptosis of ATDC5 cells (Itoh 2008)
  • zinc binding involved in skeletal development
  • regulates osteocalcin expression and modulates mineralized bone matrix formation (Piscopo 2009)
  • is a novel regulator of the Wnt signaling pathway and of early hair follicle progenitors in the developing vibrissa follicle
  • TRPS1 directly represses expression of the hair follicle stem cell regulator SOX9 to control proliferation of the follicle epithelium
  • multi zinc-finger nuclear regulator of chondrocyte proliferation and differentiation
  • acts as regulator of histone deacetylation
  • GATA-type transcription factor that acts as a transcriptional repressor
  • is required for odontoblast maturation by supporting expression of genes crucial for initiating the mineralization process, and represses the function of mature cells and, consequently, restricts the extent of extracellular matrix mineralization
  • atypical GATA factor, modulating cell proliferation and controling cell cycle progression
  • acts as a central hub in the control of cell cycle and proliferation during cancer development
  • is a potent regulator of proliferation, differentiation, and apoptosis
  • CELLULAR PROCESS cell life, cell death/apoptosis

    a component
  • can directly bind to the osteocalcin promoter independently of the presence of RUNX2, through a GATA binding sequence (Piscopo 2009)
  • RNA
    small molecule metal binding,
  • Zn2+ binding
  • protein
  • with DNCL1 (suppression of repressor activity)
  • interacting with RNF4
  • interacts with RUNX2 and represses RUNX2-mediated trans-activation
  • repressor of STAT3 expression, which in turn controls chondrocyte proliferation and survival by regulating the expression of cyclin D1 and BCL2 (Suemoto 2007)
  • transcriptional control by IRX5 is modulated by direct protein-protein interaction with two GATA zinc-finger proteins, GATA3 and TRPS1
  • TRPS1 interacts with two histone deacetylases, HDAC1 and HDAC4, thereby increasing their activity
  • CTSD also binds to full-length TRPS1
  • TRPS1 acting as a transcription activator, directly induced FOXA1 transcription by binding to the FOXA1 promoter

    Therapy target
  • mice with a disrupted Trps1 gene develop a chondrodysplasia characterized by diminished chondrocyte proliferation and decreased apoptosis in growth plates (Suemoto 2007)
  • lLoss of Trps1 in mice leads to an increased proportion of cells arrested in mitosis and, subsequently, to chromosome segregation defects
  • hair follicle development in Trps1 KO embryos is impaired directly or indirectly by decreased Noggin expression
