Involved in transcriptional regulation, through association with histone acetyltransferase (HAT) SAGA-type complexes like the TFTC-HAT, ATAC or STAGA complexes. Specifically recognizes and binds methylated 'Lys-4' of histone H3 (H3K4me), with a preferrence for trimethylated form (H3K4me3). In the SAGA-type complexes, required to recruit complexes to H3K4me. May be involved in MYC-mediated oncogenic transformation.
Belongs to the SGF29 family. Contains 1 SGF29 C-terminal domain.
The SGF29 tudor-like domain mediates binding to methylated 'Lys-4' of histone H3 (H3K4me).
