 94-186 2.54e-27

Middle domain of the origin recognition complex subunit 6; Orc6 is a subunit of the origin recognition complex in eukaryotes, and it may be involved in binding to DNA. This model describes the central or middle domain of Orc6, whose structure resembles that of TFIIB, a DNA-binding transcription factor. Orc6 appears to form distinct complexes with DNA, and a putative DNA-binding site has been identified.

 199-249 1.91e-13

C-terminal domain of the eukaryotic origin recognition complex subunit ORC6; In eukaryotes, a complex consisting of six subunits promotes the onset of DNA replication. The 6th subunit, ORC6, does not belong to the wider AAA+ family of nucleotide hydrolases, but contains a tandemly repeated domain resembling the transcription factor TFIIB, as well as this C-terminal domain which harbors a helical segment that is responsible for interactions with the complex by binding to ORC3. Mutations in this C-terminal helix interfere with the formation of the ORC and have been linked to Meier-Gorlin syndrome, a dwarfism disorder.

 6-94 4.78e-15

Origin recognition complex subunit 6 (ORC6); This family consists of several eukaryotic origin recognition complex subunit 6 (ORC6) proteins. Despite differences in their structure and sequences among eukaryotic replicators, ORC is a conserved feature of replication initiation in all eukaryotes. ORC-related genes have been identified in organizms ranging from S. pombe to plants to humans. All DNA replication initiation is driven by a single conserved eukaryotic initiator complex termed he origin recognition complex (ORC). The ORC is a six protein complex. The function of ORC is reviewed in.
