Summaries for ORC4 Gene

Entrez Gene Summary for ORC4 Gene

  • The origin recognition complex (ORC) is a highly conserved six subunit protein complex essential for the initiation of the DNA replication in eukaryotic cells. Studies in yeast demonstrated that ORC binds specifically to origins of replication and serves as a platform for the assembly of additional initiation factors such as Cdc6 and Mcm proteins. This gene encodes a subunit of the ORC complex. Several alternatively spliced transcript variants, some of which encode the same protein, have been reported for this gene.

GeneCards Summary for ORC4 Gene

ORC4 (Origin Recognition Complex, Subunit 4) is a Protein Coding gene. Diseases associated with ORC4 include meier-gorlin syndrome 2 and meier-gorlin syndrome 1. Among its related pathways are Cell Cycle, Mitotic and Cell Cycle, Mitotic. GO annotations related to this gene include nucleotide binding and DNA replication origin binding.

UniProtKB/Swiss-Prot for ORC4 Gene

  • Component of the origin recognition complex (ORC) that binds origins of replication. DNA-binding is ATP-dependent. The specific DNA sequences that define origins of replication have not been identified yet. ORC is required to assemble the pre-replication complex necessary to initiate DNA replication. Binds histone H3 and H4 trimethylation marks H3K9me3, H3K27me3 and H4K20me3.

  • Meier-Gorlin syndrome 2 (MGORS2) [MIM:613800]: A syndrome characterized by bilateral microtia, aplasia/hypoplasia of the patellae, and severe intrauterine and postnatal growth retardation with short stature and poor weight gain. Additional clinical findings include anomalies of cranial sutures, microcephaly, apparently low-set and simple ears, microstomia, full lips, highly arched or cleft palate, micrognathia, genitourinary tract anomalies, and various skeletal anomalies. While almost all cases have primordial dwarfism with substantial prenatal and postnatal growth retardation, not all cases have microcephaly, and microtia and absent/hypoplastic patella are absent in some. Despite the presence of microcephaly, intellect is usually normal. {ECO:0000269 PubMed:21358631, ECO:0000269 PubMed:21358632}. Note=The disease is caused by mutations affecting the gene represented in this entry.
