Protein: Transcriptional regulator Kaiso (Zinc finger and BTB domain-containing protein 33) (xKaiso) (Q8UVQ4)
Organism: Xenopus laevis (African clawed frog)
Function: Transcriptional regulator with bimodal DNA-binding specificity. Binds to methylated CpG dinucleotides in the consensus sequence 5'-CGCG-3' and also binds to the non-methylated consensus sequence 5'-CTGCNA-3'. May recruit the N-CoR repressor complex to promote histone deacetylation and the formation of repressive chromatin structures in target gene promoters. Contributes to the repression of target genes of the Wnt signaling pathway and to the methylation-dependent repression of zygotic transcription prior to the mid-blastula transition (MBT). Also required for gastrulation movements.
Subcellular location: Nucleus.
