Cloning and expression analysis of a novel WD repeat gene, WDR3, mapping to 1p12-p13.
WD repeat proteins are components of multiprotein complexes that are involved in a wide spectrum of cellular activities, such as cell cycle progression, signal transduction, apoptosis, and gene regulation. These proteins are characterized by repeat units bracketed by Gly-His and Trp-Asp (GH-WD). We report here the isolation of a new member of the WD repeat gene family, WDR3, which encodes a putative 943-amino-acid nuclear protein consisting of 10 WD repeat modules. WDR3 is widely expressed in hematopoietic cell lines and in nonhematopoietic tissues. Fluorescence in situ hybridization mapped WDR3 to human chromosome 1p12-p13, a region that is affected by chromosomal rearrangements in a number of hematologic malignancies and solid tumors.
