Component of the origin recognition complex (ORC) that binds origins of replication. It has a role in both chromosomal replication and mating type transcriptional silencing. Binds to the ARS consensus sequence (ACS) of origins of replication. Component of the origin recognition complex (ORC) composed of at least ORC1, ORC2, ORC3, ORC4, ORC5 and ORC6. Interacts with ORC3, ORC5 and TAH11. Present with 2970 molecules/cell in log phase SD medium. Belongs to the ORC6 family. It is uncertain whether Met-1 or Met-3 is the initiator. Truncated N-terminus.
