molecular function
    GO:0003677    DNA binding    Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
    GO:0051059    NF-kappaB binding    Interacting selectively and non-covalently with NF-kappaB, a transcription factor for eukaryotic RNA polymerase II promoters.
    GO:0000978    RNA polymerase II core promoter proximal region sequence-specific DNA binding    Interacting selectively and non-covalently with a sequence of DNA that is in cis with and relatively close to a core promoter for RNA polymerase II.
    GO:0000980    RNA polymerase II distal enhancer sequence-specific DNA binding    Interacting selectively and non-covalently with a RNA polymerase II (Pol II) distal enhancer. In mammalian cells, enhancers are distal sequences that increase the utilization of some promoters, and can function in either orientation and in any location (upstream or downstream) relative to the core promoter.
    GO:0000977    RNA polymerase II regulatory region sequence-specific DNA binding    Interacting selectively and non-covalently with a specific sequence of DNA that is part of a regulatory region that controls the transcription of a gene or cistron by RNA polymerase II.
    GO:0042805    actinin binding    Interacting selectively and non-covalently with actinin, any member of a family of proteins that crosslink F-actin.
    GO:0033613    activating transcription factor binding    Interacting selectively and non-covalently with an activating transcription factor, any protein whose activity is required to initiate or upregulate transcription.
    GO:0071532    ankyrin repeat binding    Interacting selectively and non-covalently with an ankyrin repeat of a protein. Ankyrin repeats are tandemly repeated modules of about 33 amino acids; each repeat folds into a helix-loop-helix structure with a beta-hairpin/loop region projecting out from the helices at a 90-degree angle, and repeats stack to form an L-shaped structure.
    GO:0031490    chromatin DNA binding    Interacting selectively and non-covalently with DNA that is assembled into chromatin.
