Chain A,C (PRI1_HUMAN | P49642)

molecular function
	GO:0003896	DNA primase activity	Catalysis of the synthesis of a short RNA primer on a DNA template, providing a free 3'-OH that can be extended by DNA-directed DNA polymerases.
	GO:0003899	DNA-directed 5'-3' RNA polymerase activity	Catalysis of the reaction: nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1). Utilizes a DNA template, i.e. the catalysis of DNA-template-directed extension of the 3'-end of an RNA strand by one nucleotide at a time. Can initiate a chain 'de novo'.
	GO:0046872	metal ion binding	Interacting selectively and non-covalently with any metal ion.
	GO:0016779	nucleotidyltransferase activity	Catalysis of the transfer of a nucleotidyl group to a reactant.
	GO:0016740	transferase activity	Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
biological process
	GO:0006260	DNA replication	The cellular metabolic process in which a cell duplicates one or more molecules of DNA. DNA replication begins when specific sequences, known as origins of replication, are recognized and bound by initiation proteins, and ends when the original DNA molecule has been completely duplicated and the copies topologically separated. The unit of replication usually corresponds to the genome of the cell, an organelle, or a virus. The template for replication can either be an existing DNA molecule or RNA.
	GO:0006270	DNA replication initiation	The process in which DNA-dependent DNA replication is started; this involves the separation of a stretch of the DNA double helix, the recruitment of DNA polymerases and the initiation of polymerase action.
	GO:0006269	DNA replication, synthesis of RNA primer	The synthesis of a short RNA polymer, usually 4-15 nucleotides long, using one strand of unwound DNA as a template; the RNA then serves as a primer from which DNA polymerases extend synthesis.
	GO:0006271	DNA strand elongation involved in DNA replication	The process in which a DNA strand is synthesized from template DNA during replication by the action of polymerases, which add nucleotides to the 3' end of the nascent DNA strand.
	GO:0000082	G1/S transition of mitotic cell cycle	The mitotic cell cycle transition by which a cell in G1 commits to S phase. The process begins with the build up of G1 cyclin-dependent kinase (G1 CDK), resulting in the activation of transcription of G1 cyclins. The process ends with the positive feedback of the G1 cyclins on the G1 CDK which commits the cell to S phase, in which DNA replication is initiated.
	GO:0000722	telomere maintenance via recombination	Any recombinational process that contributes to the maintenance of proper telomeric length.
cellular component
	GO:0016020	membrane	A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
	GO:0005654	nucleoplasm	That part of the nuclear content other than the chromosomes or the nucleolus.
	GO:1990077	primosome complex	Any of a family of protein complexes that form at the origin of replication or stalled replication forks and function in replication primer synthesis in all organisms. Early complexes initiate double-stranded DNA unwinding. The core unit consists of a replicative helicase and a primase. The helicase further unwinds the DNA and recruits the polymerase machinery. The primase synthesizes RNA primers that act as templates for complementary stand replication by the polymerase machinery. The primosome contains a number of associated proteins and protein complexes and contributes to the processes of replication initiation, lagging strand elongation, and replication restart.

Chain B,D (PRI2_HUMAN | P49643)

molecular function
	GO:0051539	4 iron, 4 sulfur cluster binding	Interacting selectively and non-covalently with a 4 iron, 4 sulfur (4Fe-4S) cluster; this cluster consists of four iron atoms, with the inorganic sulfur atoms found between the irons and acting as bridging ligands.
	GO:0003677	DNA binding	Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
	GO:0003896	DNA primase activity	Catalysis of the synthesis of a short RNA primer on a DNA template, providing a free 3'-OH that can be extended by DNA-directed DNA polymerases.
	GO:0003899	DNA-directed 5'-3' RNA polymerase activity	Catalysis of the reaction: nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1). Utilizes a DNA template, i.e. the catalysis of DNA-template-directed extension of the 3'-end of an RNA strand by one nucleotide at a time. Can initiate a chain 'de novo'.
	GO:0051536	iron-sulfur cluster binding	Interacting selectively and non-covalently with an iron-sulfur cluster, a combination of iron and sulfur atoms.
	GO:0046872	metal ion binding	Interacting selectively and non-covalently with any metal ion.
	GO:0016779	nucleotidyltransferase activity	Catalysis of the transfer of a nucleotidyl group to a reactant.
	GO:0016740	transferase activity	Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor).
