The Wilms tumor suppressor gene WT1 appears to play a role in both transcriptional and posttranscriptional regulation of certain cellular genes. This gene encodes a WT1-associating protein, which is a ubiquitously expressed nuclear protein. Like WT1 protein, this protein is localized throughout the nucleoplasm as well as in speckles and partially colocalizes with splicing factors. Alternative splicing of this gene results in several transcript variants encoding three different isoforms. [provided by RefSeq, Jul 2012],function:Regulates G2/M cell-cycle transition by binding to the 3 UTR of CCNA2, which enhances its stability. Impairs WT1 DNA-binding ability and inhibits expression of WT1 target genes. May be involved in mRNA splicing regulation.,induction:In smooth muscle cells, up-regulated after serum withdrawal, when cells become mature and non proliferative.,PTM:Phosphorylated upon DNA damage, probably by ATM or ATR.,similarity:Belongs to the fl(2)d family.,subunit:Interacts with WT1.,tissue specificity:Ubiquitously expressed.,
