제목 A Strategy for the Efficient Production ofBioactive Human Papillomavirus16 L1 Proteinusing Escherichia coli
초록 The major capsid protein L1 of human papillomavirus (HPV) has the intrinsic ability to form virus-like particles that induce the production of neutralizing antibodies. Therefore, HPV L1 capsid protein has been widely studied for immune response to HPV vaccine. To construct an efficient prokaryotic HPV16 L1 expression system, we attempted to produce HPV16 L1 fusion proteins using the stress-responsive proteins (SHPs) as fusion partners. Among the fusion partners, when SHP2 was fused to the N-termnus of the L1 protein, the GroEL contamination that is observed during GST fusion expression was dramatically decreased. Furthermore, ELISA analysis indicated that the SHP2- L1 fusion protein had specific binding activity toward the HPV16 L1 specific antibody, which indicates that SHP2-L1 protein had antigenic epitope that can be accessed by antibody even without the removal of fusion partner. Consequently, SHP2 fusion is an effective expression method, by which a large quantity of soluble and bioactive L1 protein is produced with simpler purification process.
