    Summary
    Enables DNA replication origin binding activity. Predicted to be involved in DNA replication initiation. Located in heterochromatin. Part of inner kinetochore and nuclear origin of replication recognition complex. Is expressed in several structures, including 1st branchial arch maxillary component; brain; genitourinary system; sensory organ; and spleen. Orthologous to human ORC2 (origin recognition complex subunit 2). [provided by Alliance of Genome Resources, Dec 2024]

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
