Anti-TRRAP Antibody, clone 2TRR-1B3

Transformation/transcription domain-associated protein (UniProt Q9Y4A5; also known as 350/400 kDa PCAF-associated factor, PAF350/400, STAF40, TR-AP, Tra1 homolog) is encoded by the TRRAP (also known as PAF400) gene (Gene ID 8295) in human. Transformation/transcription domain-associated protein (TRRAP) is a cofactor component shared by several histone acetyltransferase (HAT) complexes, including SAGA (Spt-Ada-Gcn5-acetyltransferase), PCAF (P300/CBP-associated factor), and Tip60. TRRAP is an essential component of the histone epigenetic modifying mechinery that plays an important role in regulating cell-cycle progression. Trrap gene-knockdown or protein downregulation causes cell and mouse lethality, impaired spindle checkpoint and differentiation.

~400 kDa observed. 437.6 kDa (isoform 1) and 434.4 kDa (isoform 2) calculated. Uncharacterized band(s) may appear in some lysates.

Epitope: N-terminal to nuclear localization signal in the TP53-interacting region.

Ovalbumin-conjugated linear peptide corresponding to a sequence from the TP53-interacting region of human TRRAP.

Anti-TRRAP Antibody, clone 2TRR-1B3 is an antibody against TRRAP for use in Western Blotting, Immunoprecipitation.

Immunoprecipitation Analysis: 10 µL from a representative lot immunoprecipitated TRRAP from 1 mL (4.5 mg/mL) of HeLa nuclear extract (Courtesy of Dr. Mustapha OULAD-ABDELGHANI, IGBMC, France).
Immunoprecipitation Analysis: A representative lot immunodepleted TRRAP using nonhomologous end-joining/NHEJ-competent protein extracts prepared from human AAH-1 lymphoblastoid cells (Robert, F., et al. (2006). Mol. Cell. Biol. 26(2):402-412).
