Androgen Receptor N-terminal Domain (AR-NTD)

Target: AR-NTD
Molecular classification: Transcription factor domain, Protein domain

Overview

The androgen receptor’s N-terminal domain serves as its principal regulatory hub: it orchestrates gene activation through dynamic structural features that enable diverse protein-protein interactions. Its unique properties make it both crucial for normal physiology—and a major therapeutic challenge/opportunity—in diseases like advanced prostate cancer where conventional therapies fail due to persistent or variant forms retaining active NTDs.

Other names: AR NTDNTD of Androgen ReceptorActivation Function 1 (AF1) region of AR
