NCOA2 (SRC2) Polyclonal

NCOA2 (Nuclear receptor coactivator 2) (also known as SRC2, BHLHE75, TIF2), is a 160 kDa transcriptional coactivator for steroid receptors and nuclear receptors that acts as a coactivator of the steroid binding domain (AF-2), but not the modulating N-terminal domain (AF-1). It possesses a single NR interaction domain (NID) and two autonomous activation domains, AD1 and AD2. NCOA2 assists nuclear receptors in the upregulation of DNA expression. In cells ligand activated nuclear receptors recruit NCOA2 to DNA where it acylates histones to make targeted regions accessible to transcriptional machinery. Along with NCOA1 it controls energy balance between white and brown adipose tissues and also acts as a critical regulator of glucose metabolism. It is also involved in the positive regulation of the transcriptional activity of the glucocorticoid receptor NR3C1 by sumoylation enhancer RWDD3. NCOA2 is reported to positively regulate the circadian clock by acting as a transcriptional coactivator for the CLOCK-ARNTL/BMAL1 heterodimer. Chromosomal aberrations involving NCOA2 may be a cause of acute myeloid leukemias.
