Protein chibby homolog 1 is a protein that in humans is encoded by the CBY1 gene. [5] [6] [7]

Contents

Function

Beta-catenin is a transcriptional activator and oncoprotein involved in the development of several cancers. The protein encoded by this gene interacts directly with the C-terminal region of beta-catenin, inhibiting oncogenic beta-catenin-mediated transcriptional activation by competing with transcription factors for binding to beta-catenin. Two transcript variants encoding different isoforms have been found for this gene. [7] CBY1 has also been shown to be important for ciliogenesis and is found at the transition zone of the cilium. [8]

Interactions

CBY1 has been shown to interact with Beta-catenin. [9] CBY1 has also been shown to interact with CEP164, FAM92A1, and RAB8. [8]

ZBTB33

Transcriptional regulator Kaiso is a protein that in humans is encoded by the ZBTB33 gene. This gene encodes a transcriptional regulator with bimodal DNA-binding specificity, which binds to methylated CGCG and also to the non-methylated consensus KAISO-binding site TCCTGCNA. The protein contains an N-terminal POZ/BTB domain and 3 C-terminal zinc finger motifs. It recruits the N-CoR repressor complex to promote histone deacetylation and the formation of repressive chromatin structures in target gene promoters. It may contribute to the repression of target genes of the Wnt signaling pathway, and may also activate transcription of a subset of target genes by the recruitment of catenin delta-2 (CTNND2). Its interaction with catenin delta-1 (CTNND1) inhibits binding to both methylated and non-methylated DNA. It also interacts directly with the nuclear import receptor Importin-α2, which may mediate nuclear import of this protein. Alternatively spliced transcript variants encoding the same protein have been identified.
