We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

Plant Homeodomain Finger of the tumour suppressor ING4

Overview

Plant homeodomain (PHD) fingers are frequently present in proteins, involved in chromatin remodelling, and some of them bind to histones. The, family of proteins inhibitors of growth (ING) contains a PHD finger that, bind to histone-3 trimethylated at lysine 4, and those of ING1 and ING2, also act as nuclear phosphoinositide receptors. We have determined the, structure of ING4 PHD, and characterised its binding to phosphoinositides, and histone methylated tails. In contrast to ING2, ING4 is not a, phosphoinositide receptor and binds with similar affinity to the different, methylation states of histone-3 at lysine 4.

About this Structure

2JMQ is a Single protein structure of sequence from Homo sapiens with ZN as ligand. Full crystallographic information is available from OCA.
