The alteration of DNA or protein in chromatin by the non-covalent addition or removal of chemical groups.

The process by which the anatomical structures of epithelia are generated and organized. Morphogenesis pertains to the creation of form. An epithelium is a sheet of closely packed cells arranged in one or more layers, that covers the outer surfaces of the body or lines any internal cavity or tube.

Ordering of successions of nucleosomes into regular arrays so that nucleosomes are positioned at defined distances from one another.

Any complex that mediates dynamic changes in eukaryotic chromatin.

A protein complex similar to, but more abundant than, the Swi/Snf complex. The RSC complex is generally recruited to RNA polymerase III promoters and is specifically recruited to RNA polymerase II promoters by transcriptional activators and repressors.

A protein complex that contains an ISWI-family ATPase such as Saccharomyces Isw1p, and acts to modify chromatin structure.

A four subunit ISWI-containing protein complex that facilitates nucleosome mobility and transcriptional activation in an ATP-dependent manner. In contrast to other chromatin remodeling complexes, the ATPase activity of NURF requires nucleosomes rather than free DNA or histones.

Interacting selectively with juvenile hormone, the three sesquiterpenoid derivatives that function to maintain the larval state of insects at molting and that may be required for other processes, e.g. oogenesis.

Interacting selectively with retinoids, any member of a class of isoprenoids that contain or are derived from four prenyl groups linked head-to-tail. Retinoids include retinol and retinal and structurally similar natural derivatives or synthetic compounds, but need not have vitamin A activity.

Interacting selectively with 11-cis retinal, an isomer of retinal that plays an important role in the visual process in most vertebrates. 11-cis retinal combines with opsin in the rods (scotopsin) to form rhodopsin or visual purple. Retinal is one of the three compounds that makes up vitamin A.
