Androgen Receptor Ligand Binding Domain (AR-LBD)

Target
AR-LBD
Molecular classification
Nuclear Receptor Domain, Transcription Factor Domain
01

Overview

The androgen receptor ligand binding domain (AR-LBD) is a critical region of the androgen receptor (AR), responsible for binding androgens such as testosterone and dihydrotestosterone (DHT). This binding triggers conformational changes that activate the receptor's function as a transcription factor, regulating gene expression related to male development and reproduction. Abnormalities or mutations within this domain can lead to diseases including prostate cancer, Kennedy’s disease, complete androgen insensitivity syndrome (CAIS), and male infertility.

02

Mechanism of action

Ligand binding induces conformational changes, leading to dimerization, DNA binding, and recruitment of co-regulators to modulate gene transcription.
