General annotation (Comments)

Function	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 in an ATP-dependent manner. Ref.1
Subunit structure	ORC is composed of six subunits By similarity.
Subcellular location	Nucleus By similarity.
Sequence similarities	Belongs to the ORC1 family. Contains 1 BAH domain.
