    Summary
    Predicted to enable ATP binding activity; ATP hydrolysis activity; and chromatin binding activity. Involved in DNA amplification and DNA replication initiation. Part of nuclear origin of replication recognition complex. Is expressed in several structures, including egg chamber; eye disc posterior to the morphogenetic furrow; mitotic domain; presumptive embryonic/larval system; and ventral furrow. Human ortholog(s) of this gene implicated in Meier-Gorlin syndrome 1. Orthologous to human ORC1 (origin recognition complex subunit 1). [provided by Alliance of Genome Resources, Apr 2022]
