molecular function
	GO:0043531	ADP binding	Interacting selectively and non-covalently with ADP, adenosine 5'-diphosphate.
	GO:0005524	ATP binding	Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
	GO:0016887	ATPase activity	Catalysis of the reaction: ATP + H2O = ADP + phosphate + 2 H+. May or may not be coupled to another reaction.
	GO:0003677	DNA binding	Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
	GO:0032405	MutLalpha complex binding	Interacting selectively and non-covalently with the mismatch repair complex MutLalpha.
	GO:0000403	Y-form DNA binding	Interacting selectively and non-covalently with segment of DNA shaped like a Y. This shape occurs when DNA contains a region of paired double-stranded DNA on one end and a region of unpaired DNA strands on the opposite end.
	GO:0019237	centromeric DNA binding	Interacting selectively and non-covalently with a centromere, a region of chromosome where the spindle fibers attach during mitosis and meiosis.
	GO:0003684	damaged DNA binding	Interacting selectively and non-covalently with damaged DNA.
	GO:0032139	dinucleotide insertion or deletion binding	Interacting selectively and non-covalently with double-stranded DNA containing a dinucleotide insertion or deletion.
	GO:0032181	dinucleotide repeat insertion binding	Interacting selectively and non-covalently with double-stranded DNA containing a dinucleotide repeat insertion or a deletion resulting in unpaired dinucleotide repeats.
	GO:0000406	double-strand/single-strand DNA junction binding	Interacting selectively and non-covalently with a region of DNA that contains double-stranded DNA flanked by a region of single-stranded DNA.
	GO:0003690	double-stranded DNA binding	Interacting selectively and non-covalently with double-stranded DNA.
	GO:0019899	enzyme binding	Interacting selectively and non-covalently with any enzyme.
	GO:0000400	four-way junction DNA binding	Interacting selectively and non-covalently with DNA containing four-way junctions, also known as Holliday junctions, a structure where two DNA double strands are held together by reciprocal exchange of two of the four strands, one strand each from the two original helices.

	GO:0010224	response to UV-B	Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a UV-B radiation stimulus. UV-B radiation (UV-B light) spans the wavelengths 280 to 315 nm.
