SGF29 C-terminal domain profile


Eukaryotic SGF29 is a component of histone acetyltransferase (HAT) complexes TATA-binding protein-free TAF-containing (TFTC) and SPT3-TAF9-GCN5-acetyltransferase (STAGA) or SPT-ADA-GCN5-acetyltransferase (SAGA) [1]. The SGF29 C-terminal domain contains a double Tudor-like motif that selectively binds the H3K4me2/3 lysine methylation site on the N terminus of histone H3 [2,3].

Each Tudor domain consists of five twisted anti-parallel β strands forming a typical barrel-like fold (see <PDB:3MEA>). The tandem Tudor domains tightly pack against each other face-to-face with each Tudor domain harboring a negatively charged pocket accommodating the first residue alanine and methylated K4 residue of histone H3, respectively [3].

The profile we developed covers the entire SGF29 C-terminal domain.
