Human casein kinase II subunit alpha: sequence of a processed (pseudo)gene and its localization on chromosome 11

Abstract

A human 4.3 kb genomic DNA fragment, containing the information of a processed (pseudo)gene of casein kinase II subunit alpha (CKII alpha) was isolated and sequenced. The genomic CKII alpha sequence is 99% homologous to the CKII alpha cDNA, carries several nucleotide exchanges, a poly(A) stretch at its 3' end and is flanked at both ends by a 16 bp repeat. It has a promoter-like region including two TATA boxes and a CAAT box. Although translation of transcripts would be terminated by a stop codon after two third of the coding region, the resulting protein would still contain the catalytic domains. However, so far Northern blots with a 3' specific probe were negative. The 4.3 kb genomic fragment containing the processed CKII alpha (pseudo)gene was mapped by in situ hybridization to chromosome 11p15.
