Summary: Predicted to enable DNA replication origin binding activity and chromatin binding activity. Predicted to be involved in DNA replication initiation; positive regulation of smooth muscle cell proliferation; and regulation of cell cycle process. Predicted to act upstream of or within DNA replication. Predicted to be located in nucleoplasm. Predicted to be part of nuclear origin of replication recognition complex. Predicted to colocalize with chromosome, telomeric region. Is expressed in liver and submandibular gland. 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, Jan 2025]

What's a GeneRIF?

Clearance of beta-amyloid mediated by autophagy is enhanced by MTORC1 inhibition but not AMPK activation in APP/PSEN1 astrocytes.
Title: Clearance of β-amyloid mediated by autophagy is enhanced by MTORC1 inhibition but not AMPK activation in APP/PSEN1 astrocytes.
ORC1 in mice is essential for mitotic cell divisions but dispensable for endoreduplication.
Title: Endoreduplication of the mouse genome in the absence of ORC1.
mouse Orc1, Orc2, and Orc3 each exist in two alternative-splicing variants and naturally occurring Orc1B lacks a functional domain that is essential for nuclear translocation and proteasome-dependent degradation
Title: Novel splicing variant of mouse Orc1 is deficient in nuclear translocation and resistant for proteasome-mediated degradation.

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.
