During HIV transcriptation, not only structural proteins are coded by HTV, but also some regulatory proteins including trans - activator protein Tat which is made up of 86 -130 amino acids and responsible for regulating HTV transcription are coded.

• 在HIV的复制过程中，HIV不仅编码了结构蛋白和酶蛋白，而且编码了一些辅助调节蛋白，其中包括一段由86-130个氨基酸组成的能够调节HIV转录的反式激活蛋白Tat(Trans-activator protein)。
