功能May play a role in growth regulation. Is associated with G2/M phase arrest in response to DNA damage. May be an intermediate by which p53 mediates its role as an inhibitor of cellular proliferation.
组织特异性High levels in skeletal muscle, ovary, kidney and colon.
序列相似性Belongs to the cyclin family. Cyclin G subfamily.
发展阶段Very low levels in normal cells during G1 phase, which increase as cells enter the S phase and stay high throughout the S and G2/M phases. In breast cancer cells consistent high levels are found throughout the cell cycle.
细胞定位Nucleus. DNA replication foci after DNA damage.
