TRRAP Antibody

Western blot shows lysates of MOLT‑4 human acute lymphoblastic leukemia cell line, HeLa human cervical epithelial carcinoma cell line, mouse placenta tissue, mouse uterus tissue, and rat ovary tissue. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human TRRAP Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7365) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for TRRAP at approximately 440 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background

TRRAP (Transformation/transcription domain-associated protein; also PAF350/400 and STAF40) is a 400-450 kDa member of the TRA1 subfamily, PI3/PI4 kinase family, ATM superfamily of molecules. It is a ubiquitously expressed nuclear protein that functions as a promoter of gene transcription. In particular, the activity of the E2F transcription factor family is regulated by the degree of histone acetylation. Deacetylation inhibits E2F-mediated transcription, while acetylation promotes gene transcription. TRRAP promotes histone acetylation by serving as a positive modulator/cofactor for GCN5 acetyltransferase activity. TRRAP also acts independently of GCN5. It serves as a recruiter for Skp1, a ubiquitin ligase that ubiquitates chromatin-bound beta -catenin, leading to a downregulation of Wnt-signaling activity. Human TRRAP is 3859 amino acids (aa) in length. It contains one Pro-rich region (aa 485-526), an NLS (aa 2047-2062), two FAT domains (aa 2704-3275 and 3827-3859) and a nonenzymatic PI3/PI4 kinase domain (aa 3528-3826). There are multiple potential isoform variants. They show various combinations of a deletion involving aa 1493-1510, an Ala substitution for aa 3001-3012, a 119 aa substitution for aa 3784-3859, and an 18 aa insertion after Asp3287. Over aa 3610-3859, human TRRAP shares 99% aa identity with mouse TRRAP.
