Abstract:
Alpha‐tubulin N ‐acetyltransferase 1 (ATAT1) is an acetyltransferase specific to α‐tubulin and performs important functions in many cellular processes. Bombyx mori is an economic insect and also known as a model lepidoptera insect. In this study, we cloned a B. mori ATAT1 gene ( BmATAT1) (Gen Bank accession number: XP_004932777.1). BmATAT1 contained an open reading frame (ORF) of 1,065 bp encoding 355 amino acids (aa). Expression profiling of BmATAT1 protein showed that the expression levels of BmATAT1 at different developmental stages and different tissues in fifth‐instar larvae differ. BmATAT1 was highly expressed at the egg stage and in the head of the fifth‐instar larvae. Subcellular localization showed that BmATAT1 was distributed in the cytoplasm and nucleus. Furthermore, BmATAT1 may lead to time‐dependent induction of cell cycle arrest in the G2/M phase by flow cytometry analysis. Interestingly, using site‐specific mutation, immunoprecipitation, and Western blotting, we further found a BmATAT1 acetylated site at K156, suggesting that this acetyltransferase could be regulated by acetylation itself.
