Chain A,B,C,D (Q9V4D9_DROME | Q9V4D9)

molecular function
	GO:0003677	DNA binding	Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
	GO:0003723	RNA binding	Interacting selectively and non-covalently with an RNA molecule or a portion thereof.
	GO:0003729	mRNA binding	Interacting selectively and non-covalently with messenger RNA (mRNA), an intermediate molecule between DNA and protein. mRNA includes UTR and coding sequences, but does not contain introns.
	GO:0043565	sequence-specific DNA binding	Interacting selectively and non-covalently with DNA of a specific nucleotide composition, e.g. GC-rich DNA binding, or with a specific sequence motif or type of DNA e.g. promotor binding or rDNA binding.
	GO:0003697	single-stranded DNA binding	Interacting selectively and non-covalently with single-stranded DNA.
biological process
	GO:0031935	regulation of chromatin silencing	Any process that affects the rate, extent or location of chromatin silencing.
cellular component
	GO:0005737	cytoplasm	All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
	GO:1990124	messenger ribonucleoprotein complex	A ribonucleoprotein complex containing both protein and messenger RNA (mRNA) molecules.
	GO:0005634	nucleus	A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
