Asymmetric/Biological Unit(hide GO term definitions)

Chain A (MBP1_YEAST | P39678)

molecular function
	GO:0003677	DNA binding	Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
	GO:0005515	protein binding	Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
	GO:0001077	transcriptional activator activity, RNA polymerase II core promoter proximal region sequence-specific 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 (RNAP II) in order to activate or increase the frequency, rate or extent of transcription from the RNAP II promoter.
biological process
	GO:0071931	positive regulation of transcription involved in G1/S transition of mitotic cell cycle	Any process that activates or increases transcription as part of the G1/S transition of the mitotic cell cycle.
	GO:0000083	regulation of transcription involved in G1/S transition of mitotic cell cycle	Any process that regulates transcription such that the target genes are involved in the transition between G1 and S phase of the mitotic cell cycle.
	GO:0006355	regulation of transcription, DNA-templated	Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.
	GO:0006366	transcription from RNA polymerase II promoter	The synthesis of RNA from a DNA template by RNA polymerase II, originating at an RNA polymerase II promoter. Includes transcription of messenger RNA (mRNA) and certain small nuclear RNAs (snRNAs).
	GO:0006351	transcription, DNA-templated	The cellular synthesis of RNA on a template of DNA.
cellular component
	GO:0030907	MBF transcription complex	A protein complex that binds to the Mlu1 cell cycle box (MCB) promoter element, consensus sequence ACGCGN, and is involved in regulation of transcription during the G1/S transition of the cell cycle. In Saccharomyces, the complex contains a heterodimer of the DNA binding protein Mbp1p and the activator Swi4p, and is associated with additional proteins known as Nrm1p, Msa1p, and Msa2p; in Schizosaccharomyces the complex contains Res1p, Res2p, and Cdc10p.
	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.
