The HAND domain adopts a secondary structure consisting of four alpha helices, three of which (H2, H3, H4) form an L-like configuration. Helix H2 runs antiparallel to helices H3 and H4, packing closely against helix H4, whilst helix H1 reposes in the concave surface formed by these three helices and runs perpendicular to them. The domain confers DNA and nucleosome binding properties to the protein [1].	Domain
A	PF09111	SLIDE (SLIDE)	SLIDE	The SLIDE domain adopts a secondary structure comprising a main core of three alpha-helices. It has a role in DNA binding, contacting DNA target sites similar to c-Myb (Pfam:PF00249) repeats or homeodomains [1].	Domain
