MeSH definition : Trans-acting transcription factors produced by retroviruses such as HIV. They are
nuclear proteins whose expression is required for viral replication. The tat protein
stimulates LONG TERMINAL REPEAT-driven RNA synthesis for both viral regulatory and
viral structural proteins. tat stands for trans-activation of transcription.;
MeSH synonym : tat protein; tat gene products; gene product, tat; tat gene product;
