Abstract
CCT is a chaperonin which is widely present in eukaryotic cells and mainly involves in the folding and assembly of cytoskeletal proteins β-tubulin and actin. The alpha subunit of CCT(CCTα) plays a pivotal role in the folding and assembly of cytoskeletal protein(s) as an individuals or complexes. In this study, we report cloning, characterization and expression of the CCTα of Nosema bombycis (NbCCTα) for the first time. The NbCCTα gene contains a complete ORF of 1629 bp in length that encodes a 542-amino acid polypeptide. The NbCCTα is 59.662 kDa molecular weight in size with an isoelectric point (pI) of 5.81, no signal peptide or transmembrane domain. The IFA results showed that the NbCCTα was co-localized with actin and β-tubulin in the cytoplasm, nucleus, nuclear membrane and plasma membrane of N. bombycis in the process of proliferation. qPCR analysis showed that the relative expression level of NbCCTα increased from 24 h to 96 h post-infection (hp.i) of N. bombycis, and reached the highest at 96 hp.i. The relative expression level of NbCCTα gene after RNAi was restrained at a low level from 48 hp.i to 96 hp.i. Knockdown of NbCCTα gene down-regulated the expression of Nbβ-tubulin and Nbactin genes. These results imply that NbCCTα may play an important role in the lifecycle of N. bombycis.
