Description The gene ORC2 encodes for the subunit 2 of the origin recognition complex (ORC) that governs the initiation site of DNA replication and formation of the prereplication complex. It is a homolog of ORC2 from maize (AAL10453), Arabidopsis (AAM65731) and human (Q13416). It is expressed abundantly in abundant in roots, seedling and inflorescence meristem. Its expression is not correlated with cell proliferation. Compared to metazoan homologs, the plant homologs including rice ORC2, lack putative Cdks sites for phosphoryaltion in their N-terminal region.
Curator Comment Expressed in much lower amounts in mature leaves and shoot. The other subunits of the origin recognition complex (ORC) are ORC1, ORC3, ORC4 and ORC5. In animals and yeast there is a sixth subunit called ORC6.
