title: Identification and characterization of a novel murine multigene family containing a PHD-finger-like motif.
abstract: The genes Phf5a and Phf5b-ps are the first two members of a novel murine multigene family that is highly conserved during evolution and belongs to the superfamily of PHD-finger genes. The Phf5 gene family contains an active locus on mouse chromosome 15, region E and several processed pseudogenes on different chromosomes. The active locus, Phf5a, is expressed ubiquitously in pre- and postnatal murine tissues and encodes a protein of 110 amino acids. The protein is localized in the nucleus in a non-homogenous pattern as the nucleolar subcompartment is almost free of Phf5a. The molecular and biological functions of Phf5a are unknown up-to-date, but the systematic deletion of its yeast homolog is lethal, pointing out that the protein is required for cell viability. Interpretation of our data and review of the literature suggest both basic and essential cellular functions of the Phf5a protein, possibly acting as a chromatin-associated protein.
