Evidence for the simultaneous expression of alternatively spliced alkylpurine N-glycosylase transcripts in human tissues and cells

A PendleburyJ A Rafferty


We have isolated a novel human alkylpurine N-glycosylase (APNG) cDNA from a placental library by screening with an oligonucleotide based on the published sequence of the human liver cDNA encoding this protein. The nucleotide sequences of the two cDNAs were essentially identical, but the 5' untranslated region of the new sequence was truncated and the 5'-terminal 92 nucleotides of the novel cDNA were different, indicating the possibility of alternative transcripts. This region included a portion of the open reading frame, so that the predicted protein was truncated and the seven N-terminal amino acids differed from the published sequence for APNG. PCR amplification of reverse transcribed mRNA, using 5' primers unique to the two cDNAs and a common 3' primer showed that the alternative transcripts can be co-expressed in the same cells and tissues.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
