Abstract excerpt
ING proteins interact with core histones through their plant homeodomains (PHDs) and with histone acetyltransferase (HAT) and histone deacetylase (HDAC) complexes to alter chromatin structure. Here we identify a lamin interaction domain (LID) found only in ING proteins, through which they bind to and colocalize with lamin A. Lamin knockout (LMNA(-/-)) cells show reduced levels of ING1 that mislocalize. Ectopic...
