Ctnnb1 function
Catenin beta-1, also known as beta-catenin (β-catenin), is a protein that in humans is encoded by the CTNNB1 gene. Beta-catenin is a dual function protein, involved in regulation and coordination of cell–cell adhesion and gene transcription. In humans, the CTNNB1 protein is encoded by the CTNNB1 gene. In … See more Beta-catenin was initially discovered in the early 1990s as a component of a mammalian cell adhesion complex: a protein responsible for cytoplasmatic anchoring of cadherins. But very soon, it was realized that … See more Protein structure The core of beta-catenin consists of several very characteristic repeats, each approximately 40 amino acids long. Termed armadillo repeats, all these elements fold together into a single, rigid protein domain with … See more Role in depression Whether or not a given individual's brain can deal effectively with stress, and thus their susceptibility to depression, depends on the beta-catenin in each person's brain, according to a study conducted at the Icahn School of … See more • Kikuchi A (February 2000).
