Enhances the androgen receptor transcriptional activity in prostate cancer cells. Ligand-independent coactivator of the peroxisome proliferator-activated receptor (PPAR) gamma.
Widely expressed. Also detected in adipose tissues and in different cell lines. Isoform Beta is only expressed in testis.
Defects in NCOA4 are a cause of thyroid papillary carcinoma (TPC) [MIM:188550]. TPC is a common tumor of the thyroid that typically arises as an irregular, solid or cystic mass from otherwise normal thyroid tissue. Papillary carcinomas are malignant neoplasm characterized by the formation of numerous, irregular, finger-like projections of fibrous stroma that is covered with a surface layer of neoplastic epithelial cells. Note=A chromosomal aberration involving NCOA4 is found in thyroid papillary carcinomas. Inversion inv(10)(q11.2;q11.2) generates the RET/NCOA4 (PTC3) oncogene that has been found in sporadic and radiation-associated post-Chernobyl thyroid papillary carcinomas.
Detection: Chemiluminescence with an exposure time of 3 minutes.
Immunoprecipitation - NCOA4 antibody (ab86707)
Western Blot detection of NCOA4 in Immunoprecipitates of HeLa whole cell lysate (1 mg for IP, 20% of IP loaded) using ab86707 at 10 µg/mg lysate for IP and at 1 µg/ml for subsequent Western blot detection. Lane 2 represents control IgG IP.
Detection: Chemiluminescence with an exposure time of 30 seconds.
