MeSH Heading: G1 Phase Cell Cycle Checkpoints
Tree Number(s): G04.144.109.249; G04.144.500.320.500
Unique ID: D059585
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D059585
Scope Note: Regulatory signaling systems that control the progression of the CELL CYCLE through the G1 PHASE and allow transition to S PHASE when the cells are ready to undergo DNA REPLICATION. DNA DAMAGE, or the deficiencies in specific cellular components or nutrients may cause the cells to halt before progressing through G1 phase.
Entry Term(s): G1 Cell Cycle Arrest; G1 Cell Cycle Checkpoints; G1 Phase Checkpoints; G1 Phase Restriction Point; G1 Restriction Point; G1-S Phase Cell Cycle Checkpoint; START Cell Cycle Checkpoint
Previous Indexing: G1 Phase (1992-2011)
