Testis-specific chromodomain protein Y 1 is a protein that in humans is encoded by the CDY1 gene.This gene encodes a protein containing a chromodomain and a histone acetyltransferase catalytic domain. Chromodomain proteins are components of heterochromatin-like complexes and can act as gene repressors. This protein is localized to the nucleus of late spermatids where histone hyperacetylation takes place.
