CC -!- FUNCTION: Component of the origin recognition complex (ORC) that binds
CC origins of replication. DNA-binding is ATP-dependent, however specific
CC DNA sequences that define origins of replication have not been
CC identified so far. ORC is required to assemble the pre-replication
CC complex necessary to initiate DNA replication.
CC {ECO:0000256|RuleBase:RU365058}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a 5'-end (N(2),N(7)-dimethyl 5'-triphosphoguanosine)-
CC ribonucleoside in mRNA + S-adenosyl-L-methionine = a 5'-end
CC (N(2),N(2),N(7)-trimethyl 5'-triphosphoguanosine)-(ribonucleoside) in
CC mRNA + H(+) + S-adenosyl-L-homocysteine; Xref=Rhea:RHEA:67624,

CC -!- SUBUNIT: Component of the origin recognition complex (ORC) composed of
CC at least ORC1, ORC2, ORC3, ORC4, ORC5 and ORC6. ORC is regulated in a
CC cell-cycle and development dependent manner. It is sequentially
CC assembled at the exit from anaphase of mitosis and disassembled as
CC cells enter S phase. Binds unmodified and methylated histone H3.
CC {ECO:0000256|RuleBase:RU365058}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000256|ARBA:ARBA00004123,
CC ECO:0000256|RuleBase:RU365058}.
CC -!- SIMILARITY: Belongs to the ORC1 family.
CC {ECO:0000256|RuleBase:RU365058}.
CC -!- SIMILARITY: Belongs to the methyltransferase superfamily.
CC Trimethylguanosine synthase family. {ECO:0000256|ARBA:ARBA00025783}.
