Abstract

Human Papilloma Virus  (HPV) has an out standing feature for its vast intraspecies variability. Of all known 100 types or  more, 15 t ypes of them are classified as high risk  because of their occurrence  in  more than 95% of cervical cancer cases. Among all genes in their genome, E6 and E7 genes are considered oncogenes and have close relevance with their pathogenicity, whilst L1 and L2 ge nes produce capsid proteins that directly interact with their  host  receptors.  Considering  the  importance  of  L1  and  L2  in  host-receptor  relationship,  we  tried  to investigate their molecular variability thereby uncover their specificity as Indonesian variant s. Here we reported about the conservation of L1 minor capsid protein and variability of L2 capsid protein among high-risk types Human Papilloma Virus (HPV). The results indicated that L1 DNA was relatively more conserved than its L2 counterpart Also it was indicated that the middle part of either L1 or L2 CDS‟ showed more DNA variability than those  at  their  upstream  sequences.  It  is  concluded  that  L2  middle  sequences  are  important  factors  for intraspecific variations found in HPV of Indonesian variants.   Keywords: Human Papilloma Virus (HPV), L1 gene, L2 gene, cervical cancer, high risk HPV
