Previous GeneCards Identifiers for GMNN Gene
This gene encodes a protein that plays a critical role in cell cycle regulation. The encoded protein inhibits DNA replication by binding to DNA replication factor Cdt1, preventing the incorporation of minichromosome maintenance proteins into the pre-replication complex. The encoded protein is expressed during the S and G2 phases of the cell cycle and is degraded by the anaphase-promoting complex during the metaphase-anaphase transition. Increased expression of this gene may play a role in several malignancies including colon, rectal and breast cancer. Alternatively spliced transcript variants have been observed for this gene, and two pseudogenes of this gene are located on the short arm of chromosome 16. [provided by RefSeq, Oct 2011]
GeneCards Summary for GMNN Gene
GMNN (Geminin, DNA Replication Inhibitor) is a Protein Coding gene. Diseases associated with GMNN include Meier-Gorlin Syndrome 1 and Melanoacanthoma. Among its related pathways are CDK-mediated phosphorylation and removal of Cdc6 and E2F mediated regulation of DNA replication. GO annotations related to this gene include transcription corepressor activity and repressing transcription factor binding.
UniProtKB/Swiss-Prot for GMNN Gene
Inhibits DNA replication by preventing the incorporation of MCM complex into pre-replication complex (pre-RC). It is degraded during the mitotic phase of the cell cycle. Its destruction at the metaphase-anaphase transition permits replication in the succeeding cell cycle.
Inhibits the transcriptional activity of a subset of Hox proteins, enrolling them in cell proliferative control.
