Chain A,B (HEXI1_HUMAN | O94992)

molecular function
	GO:0097322	7SK snRNA binding	Interacting selectively and non-covalently with a 7SK small nuclear RNA (7SK snRNA).
	GO:0004861	cyclin-dependent protein serine/threonine kinase inhibitor activity	Stops, prevents or reduces the activity of a cyclin-dependent protein serine/threonine kinase.
	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:0017069	snRNA binding	Interacting selectively and non-covalently with a small nuclear RNA (snRNA).
biological process
	GO:0007507	heart development	The process whose specific outcome is the progression of the heart over time, from its formation to the mature structure. The heart is a hollow, muscular organ, which, by contracting rhythmically, keeps up the circulation of the blood.
	GO:0045736	negative regulation of cyclin-dependent protein serine/threonine kinase activity	Any process that stops, prevents, or reduces the frequency, rate or extent of cyclin-dependent protein serine/threonine kinase activity.
	GO:0000122	negative regulation of transcription from RNA polymerase II promoter	Any process that stops, prevents, or reduces the frequency, rate or extent of transcription from an RNA polymerase II promoter.
	GO:0045892	negative regulation of transcription, DNA-templated	Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription.
	GO:1901798	positive regulation of signal transduction by p53 class mediator	Any process that activates or increases the frequency, rate or extent of signal transduction by p53 class mediator.
	GO:0006355	regulation of transcription, DNA-templated	Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.
	GO:0006351	transcription, DNA-templated	The cellular synthesis of RNA on a template of DNA.
cellular component
	GO:0005737	cytoplasm	All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
	GO:0005654	nucleoplasm	That part of the nuclear content other than the chromosomes or the nucleolus.
	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.
