Wd repeat-containing protein 23; wdr23

CLONING

By searching a database for sequences similar to C. elegans Wdr23, Choe et al. (2009) identified 2 splice variants of human DCAF11, which they called WDR23. The deduced 546- and 520-amino acid WDR23 isoforms differ only in the presence or absence of a 26-amino acid insert near the N terminus. Both isoforms contain 7 WD40 repeats and a conserved DW box motif that overlaps WD40 repeat 5.

GENE FUNCTION

The transcription factor Skn1 (POU2F3; 607394) protects C. elegans from stress and promotes longevity. Choe et al. (2009) showed that Wdr23 interacted with Skn1 and Ddb1 (600045) in C. elegans. Loss of Wdr23 function caused accumulation of Skn1 in intestinal nuclei, elevation of Skn1 protein levels, constitutive transcription of detoxification genes, and increased longevity and stress resistance. Wdr23 interacted with the Ddb1-Cul4 (see CUL4A; 603137) complex and presumably targeted Skn1 for proteasomal degradation. Choe et al. (2009) concluded that Wdr23 is a negative regulator of Skn1 in C. elegans.

MAPPING

Hartz (2010) mapped the DCAF11 gene to chromosome 14q11.2 based on an alignment of the DCAF11 sequence (GenBank GENBANK AF130070) with the genomic sequence (GRCh37). ... More on the omim web site
