Homologous Superfamily

Beta-catenin-interacting ICAT superfamily (IPR036911)

Short name: ICAT_sf

Overlapping entries


This domain superfamily is characteristic of eukaryotic beta-catenin-interacting (ICAT) proteins. Beta-catenin is a multifunctional protein involved in both cell adhesion and transcriptional activation. Transcription mediated by the beta-catenin/Tcf complex is involved in embryological development and is upregulated in various cancers. ICAT selectively inhibits beta-catenin/Tcf binding in vivo, without disrupting beta-catenin/cadherin interactions [PMID: 12408824]. The core structure of this domain is composed of three helices.

Protein LZIC contains a leucine zipper domain and an ICAT homologous domain, with particular conservation of residues that are used by ICAT for beta-catenin-binding [PMID: 11712074, PMID: 15932753].
