Abstract: Objective To delineate RNA binding profile of NAT10(N-acetyltransferase 10) in human chronic myelogenous leukemia cell line K562. Methods Enhanced UV crosslinking and immunoprecipitation (eCLIP) were used to capture the transcript collection bound by NAT10 in K562 cells. Data were obtained through high throughput sequencing and then analyzed with bioinformatics. The type and regions of NAT10 binding genes were identified via peak-calling and annotation. The function of the binding RNA was further explored by gene function enrichment analysis. Results NAT10 binding transcripts which were enriched in 3′UTR region, were mainly protein coding genes. Further analysis showed that they were functionally associated with DNA damage and repair. Conclusions NAT10 may regulate gene expression by binding to the 3′UTR region of mRNA associated with DNA damage repair.

Key words: N-acetyltransferase 10, K562 cells, enhanced UV crosslinking, immunoprecipitation, and high-throughput sequencing(eCLIP-seq)
