This gene is a member of a small family of genes derived from piggyBac transposable elements. The encoded protein contains a zinc-ribbon domain characteristic of transposon-derived proteins and may function as a regulator of transcription. Naturally-occurring readthrough transcription occurs between this gene and the adjacent ERCC6 gene (GeneID 2074), and results in a fusion protein that shares sequence with the product of each individual gene. The readthrough locus is represented by GeneID:101243544. There are several pseudogenes for this gene on chromosomes 4, 5 and 12. [provided by RefSeq, Mar 2013].
