Naturally occurring capsid protein variants L1 of human papillomavirus genotype 16 in Morocco.

ABSTRACT: HPV L1 protein is a corner stone in HPV structure, it's involved in the formation of the viral capsid; widely used as a systematic material and considered as the main component in vaccines development and production. The present study aims to characterize genetic variation of L1 gene of HPV 16 specimens and to evaluate in silico the impact of major variants on the epitope change affecting its conformational structure. A fragment of L1 gene from 35 HPV 16 confirmed specimens were amplified by PCR and sequenced. Overall, five amino acids residues changes were reported: T390P in 16 specimens, M425I and M431I in 2 cases, insertion of Serine at 460 and aspartic acid deletion at position 477 in all analyzed cases. The 3D generated model showed that T389P amino acid substitution is located in the
