    basic FUNCTION
  • being a transcriptional repressor acting on the C-type natriuretic peptide (CNP) promoter
  • regulating cell growth, differentiation and cell death
  • modulating the transcriptional activity of SMAD3 and SMAD4
  • normally contributes to the regulation of hematopoietic precursor cells function and is a putative tumor suppressor gene that is hypermethylated and silenced in T or NK large granular lymphocyte leukemia
  • postulated role as an enhancer of CNP transcription, suggesting that TGFbeta-induced upregulation of CNP expression in vascular smooth muscle cells may be mediated in part by increased transcription of TSC22D1
  • TSC22D1 regulates TGFB1 signaling via a positive-feedback mechanism and may contribute to myocardial fibrosis

    metabolism
    signaling
    a component
  • can form an heterodimer with TSC22D4
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • binding to Smad3 and Smad4
  • interacting with TPT1
  • interaction between fortilin and TSC22D1 prevents apoptosis via the destabilization of TSC22D1 in ovarian carcinoma cells
  • TSC22D1 facilitates TGFB1 signaling by antagonizing SMAD7 activity to increase receptor stability
  • cell & other
    REGULATION
    induced by transforming growth factor beta-1 and other growth factors.

    ANIMAL & CELL MODELS
  • targeted disruption of TSC22d1 in wild-type mice enhanced proliferation and repopulation efficiency of hematopoietic precursor cells (HPCs)
  • Fat4 and Tsc22d1 are likely candidate genes to influence formation of spontaneous pulmonary adenoma in aging male and female mice, respectively
