Both SU and TM env proteins are responsible for monkey cell tropism of simian immunodeficiency virus SIV mac.
While simian immunodeficiency virus (SIV) derived from an infectious molecular clone pMA239 is tropic and pathogenic for monkeys, the virus derived from another infectious clone pMA142 does not replicate in monkey cells. To determine genetic sequences responsible for this tropism, a series of recombinant clones were constructed from pMA142 and pMA239. The determinant in pMA239 was mapped within regions encompassing the env gene. Viruses, which carry the 239 env gene encoding surface and/or transmembrane proteins, were tropic for monkey cells.
