Q&As

What specific modification does ING3 recognize on histones, and where is this recognition mediated?

ING3 recognizes histone H3 trimethylated at Lysine 4 (H3K4me3) through the Plant HomeoDomain (PHD) present at its C-terminal region.

What structural similarity was observed between ING3’s PHD and that of its homologs?

The crystal structure of ING3’s PHD showed similarity to the PHD domains of its four homologs, suggesting a common structural motif among them.

What enzymatic activity does ING3 facilitate regarding histones H2A and H4?

ING3 facilitates acetylation of histones H2A and H4 by interacting with the NuA4-Tip60 MYST histone acetyltransferase complex.

How does the PHD of ING3 interact with histone H3K4me3?

The PHD of ING3 binds histone H3K4me3 with low-micromolar affinity, while its affinity for non-methylated histone is reduced by 54-fold.

What insights do these structural features provide regarding ING3 mutations in tumors?

The structural features explain the possible deleterious effects of ING3 mutations detected in tumors, which may disrupt its histone recognition and functional roles.

How has ING3 been characterized in relation to cancer?

ING3 has been proposed to be an oncoprotein, suggesting its potential involvement in tumorigenesis.

What structural features were observed in the crystal structure of ING3’s N-terminal domain?

The crystal structure of the N-terminal domain of ING3 revealed that it forms homodimers with an antiparallel coiled-coil fold.
