Distribution of Kaiso protein in mouse tissues.

The Kaiso protein was originally described as a BTB/POZ zinc-finger transcription factor and a p120-catenin-binding partner. It is a DNA methylation-dependent transcriptional repressor, but its biological role in mice is still unknown. Here, we characterized a Kaiso-specific antibody by examining Kaiso protein distribution by immunofluorescence microscopy in the following tissues and cell types of adult mice: skin, small intestine, mammary glands, urinary bladder, and others.
