This locus is a transcribed pseudogene with similarity to two adjacent chromosome 1 loci: phosphatidylinositol-4-phosphate 5-kinase, type I, alpha (PIP5K1A, GeneID 8394) and proteasome (prosome, macropain) 26S subunit, non-ATPase, 4 (PSMD4, GeneID 5710). The pseudogene is believed to have occurred from L1 retrotransposition into chromosome 10 of a read-through transcript between the two adjacent loci. Evidence of transcription has been found (PubMed IDs: 16344562 and 17623810), but the latter publication found no evidence that the predicted protein is translated. The NCBI RefSeq Project therefore continues to treat this as a transcribed pseudogene. [provided by RefSeq, Jan 2009].
