ins， an N-terminal HH-CC zinc fingerdomainwhich is partially responsible for multimerization， a central catalytic domain and a C-terminal domain. Both Central catalytic domain and C-terminal domains have been shown to bind both viral and cellular DNA. No crystal structure data exists with Integrase bound to its DNA substrates. HIV-1 integrase functions as a dimeror a tetramer. Additionally， several host cellular proteins interact with integrase and may facilitate the integration process.
HIV-1 Integrase p31 protein is shipped at ambient temperature.
