Supplementary information

Geminin also referred to as GMNN is a protein that regulates DNA replication. It has approximately 25 kDa mass. Geminin inhibits DNA replication by preventing the loading of the mini-chromosome maintenance complex onto DNA during the cell cycle. This function ensures that DNA replication takes place only once per cell cycle. Geminin expresses mainly in tissues with high proliferative activity such as the developing nervous system and hematopoietic cells. Its interaction with other proteins plays a significant role in controlling cell cycle progression.
Biological function summary

In a cellular context Geminin forms part of a complex with the nuclear protein Cdt1. This complex is essential in the regulation of the cell cycle's S phase. Geminin's function restricts DNA replication by binding to Cdt1 and stopping its activity which is necessary during the G1/S phase transition. By doing so it preserves the integrity of genetic information and prevents re-replication. Geminin's inhibition remains strict until it is degraded during mitosis allowing Cdt1 to resume its function in the following cell cycle.

Pathways

The regulation of Geminin is important to maintaining proper DNA replication and cell cycle integrity. Geminin plays a role in the cell cycle control pathway particularly during the G1 to S phase transition. Additionally it interfaces with other proteins like Paxillin which is involved in cell adhesion and movement. Although not directly linked in a pathway Paxillin's role in regulating cellular dynamics can influence cell cycle processes in which Geminin is involved. Geminin also serves as a K blocker relevant in maintaining genetic stability.

Aberrations in Geminin activity can lead to severe conditions such as cancer. Its overexpression or misregulation has a link to various tumor types due to its effect on uncontrolled cell proliferation. Geminin's interaction with proteins like Paxillin and Cyclin-dependent kinases also relates to cancer progression as these interactions may involve changes in cellular adhesion and cycle checkpoints. Therefore understanding Geminin's role offers valuable insight for potential therapeutic targets in oncology.

General info

Function

Inhibits DNA replication by preventing the incorporation of MCM complex into pre-replication complex (pre-RC) (PubMed : 14993212, PubMed : 20129055, PubMed : 24064211, PubMed : 9635433). It is degraded during the mitotic phase of the cell cycle (PubMed : 14993212, PubMed : 24064211, PubMed : 9635433). Its destruction at the metaphase-anaphase transition permits replication in the succeeding cell cycle (PubMed : 14993212, PubMed : 24064211, PubMed : 9635433). Inhibits histone acetyltransferase activity of KAT7/HBO1 in a CDT1-dependent manner, inhibiting histone H4 acetylation and DNA replication licensing (PubMed : 20129055). Inhibits the transcriptional activity of a subset of Hox proteins, enrolling them in cell proliferative control (PubMed : 22615398).

Sequence similarities

Belongs to the geminin family.

Post-translational modifications

Phosphorylated during mitosis. Phosphorylation at Ser-184 by CK2 results in enhanced binding to Hox proteins and more potent inhibitory effect on Hox transcriptional activity.
