Human AR (Androgen Receptor) CLIA Kit

Androgen Receptor; Dihydrotestosterone Receptor; Nuclear Receptor Subfamily 3 Group C Member 4

Uniprot ID: GDF3_HUMAN ; Reactome: R-HSA-3371497 ; Gene ID: 367

Tissue Specificity: Isoform 2 is mainly expressed in heart and skeletal muscle. Isoform 3 is expressed by basal and stromal cells of prostate (at protein level).

Function: Steroid hormone receptors are ligand-activated transcription factors that regulate eukaryotic gene expression and affect cellular proliferation and differentiation in target tissues. Transcription factor activity is modulated by bound coactivator and corepressor proteins like ZBTB7A that recruits NCOR1 and NCOR2 to the androgen response elements/ARE on target genes, negatively regulating androgen receptor signaling and androgen-induced cell proliferation. Transcription activation is also down-regulated by NR0B2. Activated, but not phosphorylated, by HIPK3 and ZIPK/DAPK3. Isoform 3 and isoform 4 lack the C-terminal ligand-binding domain and may therefore constitutively activate the transcription of a specific set of genes independently of steroid hormones.
