Predicted to enable DNA replication origin binding activity. Predicted to be involved in DNA replication initiation and regulation of DNA replication. Predicted to act upstream of or within DNA replication. Predicted to be located in chromatin; cytosol; and nucleoplasm. Predicted to be part of nuclear origin of replication recognition complex. Is expressed in several structures, including alimentary system; ganglia; genitourinary system; nasal cavity epithelium; and pharyngo-tympanic tube. Orthologous to human ORC5 (origin recognition complex subunit 5). [provided by Alliance of Genome Resources, Apr 2022]
