Anti-Androgen Receptor (N-Term) Rabbit Monoclonal Antibody (Clone RM254)

Androgen receptor is a ligand-activated transcription factor and member of the steroid hormone receptor family. It is composed of an N-terminal regulatory domain (AF-1 site), a DNA-binding domain that contains two zinc fingers, a hinge region containing a nuclear localization signal, and a C-terminal ligand-binding domain (AF-2 site). Unligated androgen receptors are localized to the cytoplasm and bound to heat shock protein 23 (Hsp23), -56, -70, and -90 in a stable conformation that facilitates androgen binding. Androgen binding induces dissociation of the Hsps and nuclear translocation of the androgen receptor where it binds to androgen response elements (AREs) and induces gene transcription. Mutations in AR, the gene encoding the androgen receptor, induce abnormalities in male development ranging from partial androgen insensitivity to complete male-to-female phenotypic sex reversal. Androgen receptor knockdown induces bone loss, complete loss of sexual behaviors, and reduced aggressive behaviors in male mice, as well as defective folliculogenesis and reduced fertility in female mice. Expression of C-terminally truncated and constitutively active androgen receptor mutants are associated with reduced progression-free survival, lower prostate-specific androgen (PSA) response rates, and shorter median overall survival in patients with castration-resistant prostate cancer. Cayman's Androgen Receptor (N-Term) Rabbit Monoclonal Antibody (Clone RM254) can be used for immunohistochemistry (IHC) and Western blot (WB) applications. The antibody recognizes the N-terminus to detect the full-length androgen receptor and its splice variants from human samples.Synonyms: AR, NR3C4, Nuclear Receptor Subfamily 3 Group C Member 4.
