PG - 195-8 AB - The full length of a gene isolated using a methylated DNA binding column as previously reported (Cross et al., 1994) has been cloned. The gene encodes 55 amino acids (6.2 kDa), and has a transcript of approximately 0.45 kb. It has 2 exons in the genome. After searching for sequence homology (BLAST), a homology to hypothetically 6.3 kDa protein located at cosmid ZK652 (protein P34660; EMBL Accession No. L14429) of C. elegans chromosome 3 was noted (51.9% amino acid homology). It has 1 site (-SQ-) for DNA-dependent protein kinase (DNA-PK) phosphorylation and 2 sites of myristilation. This novel gene is very strongly expressed (about 25.6 times) in DNA-PK-deleted human glioma cell line (M059J) 2 hrs after ultraviolet (UV) irradiation compared to the DNA-PK +/+ cell line (M059K) which expresses the gene at a relatively low level (about 7.5 times). Therefore, this result suggests that DNA-PK may negatively regulate the transcriptional level of this gene in M059K cells upon UV damage (50 J/m2), associated with cell toxicity.
