Literature-anchored findings (GeneRIF, showing 10)

  • Tsg functions as an agonist synergizing with TGF-beta to inhibit T-cell activation. (PMID:17164348)
  • interferes with BMP-mediated hepcidin expression and may act with GDF15 to dysregulate iron homeostasis in thalassemia syndromes. (PMID:19414861)
  • mutations in the twisted gastrulation homolog 1 gene are neither a common direct cause nor a frequent modifying factor for human holoprosencephaly pathologies (PMID:21227728)
  • these results suggest that BMPER and Tsg maintain a fine-tuned equilibrium that controls BMP pathway activity and is necessary for vascular cell homeostasis. (PMID:23641068)
  • Data suggest CHRD (chordin) cleavage by tolloid-like metalloproteinases is insufficient to regulate BMP(bone morphogenetic protein)/BMPR signaling; CHRD fragments and TSG (twisted gastrulation protein) contribute to inhibition of BMP/BMPR signaling. (PMID:26517884)
  • Tsg functions as a BMP-agonist by inducing conformational change in chordin making it more susceptible to tolloid cleavage and as a BMP-antagonist either independently or via a chordin-mediated mechanism. (PMID:26829466)
  • Findings indicate that twisted gastrulation homolog 1 (TWSG1) maybe serves as a tumor suppressor gene in gastric cancer and potential biomarker or therapeutic target for the diagnosis and treatment of gastric cancer. (PMID:29756996)

Twisted gastrulation protein homolog 1Q9GZX9 (reviewed: Q9GZX9)

All UniProt accessions (2): Q9GZX9, J3QS03

UniProt curated annotations — full annotation on UniProt →

Function. May be involved in dorsoventral axis formation. Seems to antagonize BMP signaling by forming ternary complexes with CHRD and BMPs, thereby preventing BMPs from binding to their receptors. In addition to the anti-BMP function, also has pro-BMP activity, partly mediated by cleavage and degradation of CHRD, which releases BMPs from ternary complexes. May be an important modulator of BMP-regulated cartilage development and chondrocyte differentiation. May play a role in thymocyte development.

Subunit / interactions. Interacts with CHRD and BMP4. This interaction enhances CHRD/BMP4 complex formation. Interacts with BMP7.

Subcellular location. Secreted.

Domain organisation. The N-terminal domain is sufficient to interact with BMP4.

Miscellaneous. May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay.

Similarity. Belongs to the twisted gastrulation protein family.
