Chromatin assembly factor 1 subunit A. The CAF-1 or chromatin assembly factor-1 consists of three subunits, and this is the first, or A. The A domain is uniquely required for the progression of S phase in mouse cells, independent of its ability to promote histone deposition but dependent on its ability to interact with HP1 - heterochromatin protein 1-rich heterochromatin domains next to centromeres that are crucial for chromosome segregation during mitosis. This HP1-CAF-1 interaction module functions as a built-in replication control for heterochromatin, which, like a control barrier, has an impact on S-phase progression in addition to DNA-based checkpoints.

Tips:  If you've navigated here from a protein, hovering over a position on the weblogo will display the corresponding protein position for that domain position. The histograms below the weblogo indicate mutations found on the domain. Red is for disease (OMIM) and blue is for SNPs. Functional Features are displayed as orange boxes under the histograms. You can choose which features are displayed in the box below. Range on the Protein: Protein ID Protein Position Domain Position:  No Conserved Features/Sites Found for CAF1A
