label: transcription antitermination factor activity, RNA binding
label_lc: transcription antitermination factor activity, rna binding
description: "Binds to RNA, typically within the nascent RNA transcript, to promote readthrough of a transcription termination site and thus extending the length of the RNA transcript produced. Examples of antitermination factors which bind the nascent RNA include the lambda N protein and the HIV-1 tat protein."
