CC -!- FUNCTION: Multifunctional protein which displays endonuclease and CC helicase activities required for initiating and directing viral DNA CC replication. Also plays a role in viral packaging and transactivation CC of several promoters. Binds site-specifically to 2-3 approximate tandem CC copies within the origins of replication (Ori), unwinds this hairpin CC region and nicks one DNA strand thereby initiating the rolling circle CC replication (RCR). Becomes covalently attached to the 5' end of the CC nick and provides a 3'OH for priming DNA synthesis. The helicase CC activity unwinds DNA in a 3'-5' direction on the longer strand. CC Participates in the transcriptional regulation of several promoters. CC {ECO:0000256|ARBA:ARBA00002892}. CC -!- SUBUNIT: Homooligomer; when bound to DNA. CC {ECO:0000256|ARBA:ARBA00011717}.
