Scientific Data Images for Human NCOA2 Antibody

Detection of Human NCOA2 antibody by Western Blot.

Detection of Human NCOA2 by Western Blot.

Western blot shows lysates of JAR human choriocarcinoma cell line, Hep3B human hepatocellular carcinoma cell line, and IMR-32 human neuroblastoma cell line. PVDF membrane was probed with 0.5 µg/mL of Sheep Anti-Human NCOA2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF8010) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for NCOA2 at approximately 160 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: NCOA2

NCOA2 (Nuclear receptor COActivator 2; also TIF2 and GRIP-1) is a 150-160 kDa, ubiquitously expressed, nuclear member of the SRC/p160 nuclear receptor (NR) coactivator family of proteins. As noted, and although NCOA2 is a coactivator of hormone nuclear receptors, it also contributes to HIF-1 alpha:Arnt driven gene transcription. With respect to NRs, it not only has intrinsic activity that directly impacts hormone receptor gene activation, but also recruits additional coactivators to the NR:p160/NCOA2 complex, imparting additional complexity to target gene expression. NCOA2 binds directly to nuclear receptors via one or more LxxLL motifs that constitute an NID (NR Interaction Domain). It further uses its C-terminus to both recruit additional coactivators such as CBP and CARM1, and to modify key chromatin sites via an intrinsic HAT activity. Human NCOA2 is 1464 amino acids (aa) in length. It contains bHLH domain (aa 26-83), a PAS region (aa 119-183), four consecutive LxxLL motifs over aa 641-882, and a C-terminal LLxxLxxxL segment (aa 1079-1087). There are five utilized Ser/Thr phosphorylation sites, and three utilized acetylation sites on Lys. NCOA2 is known to undergo translocation and fuse with KAT6A/MOZ, creating a fusion product containing aa 870-1464 of NCOA2. Over aa 1090-1247, human NCOA2 shares 94% aa sequence identity with mouse NCOA2/GRIP-1.
