Is beta catenin a protein?

Is beta catenin a protein?

2.6 Effect on Cell–Cell Adhesion Machinery β-Catenin, a multifunctional protein, was originally identified as a component of cell–cell adhesion machinery. In many cancers, mutation of Wnt pathway components leads to activation of oncogenes by β-catenin–TCF transcription factor complex [51,52].

Why is beta catenin important?

In the canonical Wnt cascade, β-catenin is the key effector responsible for transduction of the signal to the nucleus and it triggers transcription of Wnt-specific genes responsible for the control of cell fate decisions in many cells and tissues.

Is Wnt AG protein?

Our data indicate that Gα proteins are not part of the core Wnt/β-catenin signaling pathway and are not generally required for pathway transduction. Gα proteins are not required for Wnt/β-catenin signaling.

What is the beta-catenin pathway?

Canonical pathway The canonical Wnt pathway (or Wnt/β-catenin pathway) is the Wnt pathway that causes an accumulation of β-catenin in the cytoplasm and its eventual translocation into the nucleus to act as a transcriptional coactivator of transcription factors that belong to the TCF/LEF family.

What happens if there is too much beta-catenin?

We report here that overexpression of beta-catenin results in accumulation of p53, apparently through interference with its proteolytic degradation. This effect involves both Mdm2-dependent and -independent p53 degradation pathways, and is accompanied by augmented transcriptional activity of p53 in the affected cells.

What is beta-catenin signaling?

Wnt/β-catenin signaling, a highly conserved pathway through evolution, regulates key cellular functions including proliferation, differentiation, migration, genetic stability, apoptosis, and stem cell renewal.

What is Wnt beta catenin?

What is Wnt β-catenin pathway?

The canonical Wnt pathway (or Wnt/β-catenin pathway) is the Wnt pathway that causes an accumulation of β-catenin in the cytoplasm and its eventual translocation into the nucleus to act as a transcriptional coactivator of transcription factors that belong to the TCF/LEF family.

What is the tcf7l2/β-catenin complex?

Being the effector of the WNT signaling pathway, the TCF7L2/β-catenin complex is probably one of the best characterized.

What is the function of TCF7L2?

TCF7L2 is a transcription factor influencing the transcription of several genes thereby exerting a large variety of functions within the cell. It is a member of the TCF family that can form a bipartite transcription factor ( β-catenin / TCF) alongside β-catenin.

Is TCF7L2 the principal transcription factor in the embryonic neocortex?

Tcf7l2, lies on a pathway through which LKB1 acts in the beta cell to restrict insulin secretion. This work identified Tcf7L2 as the principal transcription factor mediating canonical Wnt signalling in the embryonic neocortex.

Is TCF7L2 a pleiotropic gene?

The TCF7L2 gene encoding the TCF7L2 transcription factor, exhibits multiple functions through its polymorphisms and thus, is known as a pleiotropic gene. Type 2 diabetes T2DM susceptibility is exhibited in carriers of TCF7L2 rs7903146C>T and rs290481T>C polymorphisms.
