  • four LD motifs at the N terminus
  • four LIM motifs binded to two zinc ions at the C terminus, LIM domain-containing C-terminal half binds to a conserved alternatively spliced exon in LEF/TCF transcription factors, and is sufficient to interact with AR ; LIM2 and LIM3 domains were necessary and sufficient for TGFB1I1 to form a complex with MMP14

    basic FUNCTION
  • acting as a coactivator for the androgen receptor (AR)
  • has a role in the stromal-epithelial interaction involved in fetal prostate development
  • repressor of lymphoid enhancer factor/T-cell factor (LEF1)-driven transcription
  • stromal-specific AR coactivator that has an effect on an androgen-regulated growth factor that is essential for stromal/epithelial cell communication in the prostate
  • may play very important roles in the progression of prostate cancer by the modulation of AR transactivation
  • molecular regulator for androgen sensitivity in human hair follicles
  • functions as a cell-type-specific activator of TGF-beta signaling through its ability to physically interact with and neutralize SMAD7
  • its expression contributes to prostate tumorigenesis and castrate responsiveness
  • transforming growth factor-beta-inducible LIM protein whose deregulation is implicated in the progression of prostate cancer
  • roles for paxillin and TGFB1I1 in RAC1 and RHOA-dependent cell adhesion formation and maturation, processes essential for productive cell migration
  • is a versatile coregulator that acts by multiple gene-specific mechanisms that influence genomic occupancy of NR3C1 as well transcription complex assembly
  • because of its tissue-specific expression, could contribute to tissue-specific genomic occupancy and gene regulation by Steroid receptors (SRs)
  • important role in regulation of aqueous humor (AH) outflow through the trabecular meshwork (TM) in both normal and glaucomatous eyes
  • is required for the mechanically dependent generation of stress fibers in response to TGFB1
  • TGFB1I1 and HIPK1 assist MYB in recruiting the coactivator and acetyltransferase EP300 to chromatin
  • CELLULAR PROCESS cell life, cell death/apoptosis
    signaling signal transduction
    a component
    small molecule
  • can bind to AR in a ligand-dependent manner
  • can bind to the transforming growth factor-beta (TGF-beta)-signaling regulator SMAD3, thereby inhibiting certain SMAD3-dependent TGF-beta responses
  • can also control TGF-beta responses through an alternative mechanism involving SMAD7, a key negative regulator of TGF-beta signaling
  • binds to SMAD1, SMAD5 and SMAD9, and represses bone morphogenetic protein (BMP) signaling responses
  • physical and mutual functional interaction between TGFB1I1 and the BMP signaling pathway
  • CBLC interacting protein (binding leads to an increase in the ubiquitin ligase activity of CBLC once CBLC has been activated by SRC phosphorylation or through an activating phosphomimetic mutation)
  • TGFB1I1 serves as a novel scaffold protein that specifically activates MAP2K4/MAPK8 pathway, thereby leading to the induction and activation of MMP in smooth muscle cells and subsequent abdominal aortic aneurysm (AAA) formation
  • endogenous TGFB1I1 suppresses senescence and profibrotic activities of myofibroblasts by down-regulating NOX4 protein expression
  • TGFB1I1 and HSPB1, HSPB2 are effectors of NOX4 required for TGFB1-stimulated Focal adhesions (FAs) formation, adhesion strength and migration in vascular smooth muscle cell
  • TGFB1I1 is required for myofibroblast differentiation by regulating mechanically dependent MKL1 nuclear accumulation
  • appears to enhance complex formation between MMP14 and PTK2 in activated endothelial cells, which likely coordinates matrix proteolysis and cell motility
  • TGFB1I1 is a novel interaction partner of the nuclear kinase HIPK1 and TGFB1I1, like HIPK1, also interacts with the transcription factor MYB
