WD repeat-containing protein 3 is a protein that in humans is encoded by the WDR3 gene.^[1][2]

This gene encodes a nuclear protein containing 10 WD repeats. WD repeats are approximately 30- to 40-amino acid domains containing several conserved residues, which usually include a trp-asp at the C-terminal end. Proteins belonging to the WD repeat family are involved in a variety of cellular processes, including cell cycle progression, signal transduction, apoptosis, and gene regulation.^[2]

Model organisms have been used in the study of WDR3 function. A conditional knockout mouse line, called Wdr3^{tm1a(KOMP)Wtsi[7][8]} was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists.^[9][10][11]

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.^[5][12] Twenty four tests were carried out on mutant mice and two significant abnormalities were observed.^[5] No homozygous mutant embryos were identified during gestation, and therefore none survived until weaning. The remaining tests were carried out on heterozygous mutant adult mice; no additional significant abnormalities were observed in these animals. ^[5]
