In particular, N-terminal domain (NTD) of HIV-1 CA has been frequently and well reported to bind to various host cell proteins that considerably affect viral replication potential. In this study, in order to better define biological bases of the CA-NTD for HIV-1 replication, we performed an extensive mutational analysis in an unprecedented manner. By aligning CA-NTD sequences derived from representative infectious molecular clones of HIV-1, HIV-2, and simian immunodeficiency virus isolated from the rhesus macaque (SIVmac), a number of amino acids specific to HIV-1 were selected, and were replaced with those from SIVmac at the corresponding sites. Mutant viruses thus generated were then examined for multi-cycle infectivity, single-cycle infectivity, and ability to produce progeny virions. While some CA-NTD mutations affected viral replication ability to varying degrees, those in helix 7 abolished viral growth potential without exception. These results highlight functional importance of non-conserved amino acids in helix 7, and give new insights into functionality of HIV-1 CA-NTD.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Faculty of Medicine
