	The crooked neck (crn) gene of Drosophila encodes a protein of 702 amino acids and contains 16 tandemly arranged copies of a 34-amino-acid repeat that is similar to the tetratrico peptide repeat (TPR). Multiple copies of the TPR motif have also been found in a family of yeast genes, including several members that are necessary for cell division. TPR-containing proteins encoded by the yeast genes CDC16, CDC23, and nuc2+ are required for progression through the G2/M transition of the cell cycle. Loss of zygotic expression of crn causes defects in the proliferation of brain neuroblasts and results in the absence of identified neuronal lineages in the central and peripheral nervous systems. The sequence similarity and mutant phenotypes are consistent with a cell cycle requirement for the crn gene product.
