title: The human gene (CSNK2A1) coding for the casein kinase II subunit alpha is located on chromosome 20 and contains tandemly arranged Alu repeats.
abstract: We have isolated and characterized a 18.9-kb genomic clone representing a central portion of the human casein kinase II (CKII) subunit alpha gene (CSNK2A1). Using the whole clone as a probe, the gene was localized on chromosome 20p13. The clone contains eight exons whose sequences comprise bases 102 to 824 of the coding region of the human CKII alpha. The exon/intron splice junctions conform to the gt/ag rule. Three of the nine introns are located at positions corresponding to those in the CKII alpha gene of the nematode Caenorhabditis elegans. The introns contain eight complete and eight incomplete Alu repeats. Some of the Alu sequences are arranged in tandems of two or three, which seem to originate from insertions of younger Alu sequences into the poly(A) region of previously integrated Alu sequences, as indicated by flanking direct repeats.
