Replication-dependent marking of DNA by PCNA facilitates CAF-1-coupled inheritance of chromatin. (1/113)

Chromatin assembly factor 1 (CAF-1) is required for inheritance of epigenetically determined chromosomal states in vivo and promotes assembly of chromatin during DNA replication in vitro. Herein, we demonstrate that after DNA replication, replicated, but not unreplicated, DNA is also competent for CAF-1-dependent chromatin assembly. The proliferating cell nuclear antigen (PCNA), a DNA polymerase clamp, is a component of the replication-dependent marking of DNA for chromatin assembly. The clamp loader, replication factor C (RFC), can reverse this mark by unloading PCNA from the replicated DNA. PCNA binds directly to p150, the largest subunit of CAF-1, and the two proteins colocalize at sites of DNA replication in cells. We suggest that PCNA and CAF-1 connect DNA replication to chromatin assembly and the inheritance of epigenetic chromosome states.  (+info)

WD repeats of the p48 subunit of chicken chromatin assembly factor-1 required for in vitro interaction with chicken histone deacetylase-2. (2/113)

Chromatin assembly factor-1 (CAF-1) is essential for chromatin assembly in eukaryotes, and comprises three subunits of 150 kDa (p150), 60 kDa (p60), and 48 kDa (p48). We cloned and sequenced cDNA encoding the small subunit of the chicken CAF-1, chCAF-1p48. It consists of 425 amino acid residues including a putative initiation Met, possesses seven WD repeat motifs, and contains only one amino acid change relative to the human and mouse CAF-1p48s. The immunoprecipitation experiment followed by Western blotting revealed that chCAF-1p48 interacts with chicken histone deacetylases (chHDAC-1 and -2) in vivo. The glutathione S-transferase pulldown affinity assay revealed the in vitro interaction of chCAF-1p48 with chHDAC-1, -2, and -3. We showed that the p48 subunit tightly binds to two regions of chHDAC-2, located between amino acid residues 82-180 and 245-314, respectively. We also established that two N-terminal, two C-terminal, or one N-terminal and one C-terminal WD repeat motif of chCAF-1p48 are required for this interaction, using deletion mutants of the respective regions. These results suggest that chCAF-1p48 is involved in many aspects of DNA-utilizing processes, through alterations in the chromatin structure based on both the acetylation and deacetylation of core histones.  (+info)

Nucleosomes are preferentially assembled on replicating DNA by chromatin assembly factor 1; recent studies have shown that replicated DNA is marked for assembly into chromatin by the replication-fork-associated protein PCNA.  (+info)

Chromatin assembly during DNA replication in somatic cells. (4/113)

Newly replicated DNA is assembled into chromatin through two principle pathways. Firstly, parental nucleosomes segregate to replicated DNA, and are transferred directly to one of the two daughter strands during replication fork passage. Secondly, chromatin assembly factors mediate de-novo assembly of nucleosomes on replicating DNA using newly synthesized and acetylated histone proteins. In somatic cells, chromatin assembly factor 1 (CAF-1) appears to be a key player in assembling new nucleosomes during DNA replication. It provides a molecular connection between newly synthesized histones and components of the DNA replication machinery during the S phase of the cell division cycle.  (+info)

Heterochromatin dynamics in mouse cells: interaction between chromatin assembly factor 1 and HP1 proteins. (5/113)

Mechanisms contributing to the maintenance of heterochromatin in proliferating cells are poorly understood. We demonstrate that chromatin assembly factor 1 (CAF-1) binds to mouse HP1 proteins via an N-terminal domain of its p150 subunit, a domain dispensable for nucleosome assembly during DNA replication. Mutations in p150 prevent association with HP1 in heterochromatin in cells that are not in S phase and the formation of CAF-1-HP1 complexes in nascent chromatin during DNA replication in vitro. We suggest that CAF-1 p150 has a heterochromatin-specific function distinct from its nucleosome assembly function during S phase. Just before mitosis, CAF-1 p150 and some HP1 progressively dissociate from heterochromatin concomitant with histone H3 phosphorylation. The HP1 proteins reassociate with chromatin at the end of mitosis, as histone H3 is dephosphorylated.  (+info)

Duplication and maintenance of heterochromatin domains. (6/113)

To investigate the mechanisms that assure the maintenance of heterochromatin regions, we took advantage of the fact that clusters of heterochromatin DNA replicate late in S phase and are processed in discrete foci with a characteristic nuclear distribution. At the light microscopy level, within these entities, we followed DNA synthesis, histone H4 acetylation, heterochromatin protein 1 (Hp1alpha and -beta), and chromatin assembly factor 1 (CAF-1). During replication, Hp1alpha and -beta domains of concentration are stably maintained, whereas heterochromatin regions are enriched in both CAF-1 and replication-specific acetylated isoforms of histone H4 (H4Ac 5 and 12). We defined a time window of 20 min for the maintenance of this state. Furthermore, treatment with Trichostatin A (TSA), during and after replication, sustains the H4Ac 5 and 12 state in heterochromatin excluding H4Ac 8 and 16. In comparison, early replication foci, at the same level, did not display any specific enrichment in H4Ac 5 and 12. These data emphasize the specific importance for heterochromatin of the replication-associated H4 isoforms. We propose that perpetuation of heterochromatin involves self-maintenance factors, including local concentration of Hp1alpha and -beta, and that a degree of plasticity is provided by the cycle of H4 acetylation/deacetylation assisted by CAF-1.  (+info)

A CAF-1-PCNA-mediated chromatin assembly pathway triggered by sensing DNA damage. (7/113)

Sensing DNA damage is crucial for the maintenance of genomic integrity and cell cycle progression. The participation of chromatin in these events is becoming of increasing interest. We show that the presence of single-strand breaks and gaps, formed either directly or during DNA damage processing, can trigger the propagation of nucleosomal arrays. This nucleosome assembly pathway involves the histone chaperone chromatin assembly factor 1 (CAF-1). The largest subunit (p150) of this factor interacts directly with proliferating cell nuclear antigen (PCNA), and critical regions for this interaction on both proteins have been mapped. To isolate proteins specifically recruited during DNA repair, damaged DNA linked to magnetic beads was used. The binding of both PCNA and CAF-1 to this damaged DNA was dependent on the number of DNA lesions and required ATP. Chromatin assembly linked to the repair of single-strand breaks was disrupted by depletion of PCNA from a cell-free system. This defect was rescued by complementation with recombinant PCNA, arguing for role of PCNA in mediating chromatin assembly linked to DNA repair. We discuss the importance of the PCNA-CAF-1 interaction in the context of DNA damage processing and checkpoint control.  (+info)

Distinct importin recognition properties of histones and chromatin assembly factors. (8/113)

Synthesis of the protein components of nuclear chromatin occurs in the cytoplasm, necessitating specific import into the nucleus. Here, we report the binding affinities of the nuclear localisation sequence (NLS)-binding importin subunits for a range of histones and chromatin assembly factors. The results suggest that import of histones to the nucleus may be mediated predominantly by importin beta1, whereas the import of the other components probably relies on the conventional alpha/beta1 import pathway. Differences in recognition by importin beta1 were observed between histone H2A and the variant H2AZ, as well as between histone H3/4 with or without acetylation. The results imply that different histone variants may possess distinct nuclear import properties, with acetylation possibly playing an inhibitory role through NLS masking.  (+info)

Mitochondrial diseases can affect anyone, regardless of age or gender, and they can be caused by mutations in either the mitochondrial DNA (mtDNA) or the nuclear DNA (nDNA). These mutations can be inherited from one's parents or acquired during embryonic development.

Some of the most common symptoms of mitochondrial diseases include:

1. Muscle weakness and wasting
2. Seizures
3. Cognitive impairment
4. Vision loss
5. Hearing loss
6. Heart problems
7. Neurological disorders
8. Gastrointestinal issues
9. Liver and kidney dysfunction

Some examples of mitochondrial diseases include:

1. MELAS syndrome (Mitochondrial Myopathy, Encephalopathy, Lactic Acidosis, and Stroke-like episodes)
2. Kearns-Sayre syndrome (a rare progressive disorder that affects the nervous system and other organs)
3. Chronic progressive external ophthalmoplegia (CPEO), which is characterized by weakness of the extraocular muscles and vision loss
4. Mitochondrial DNA depletion syndrome, which can cause a wide range of symptoms including seizures, developmental delays, and muscle weakness.
5. Mitochondrial myopathy, encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS)
6. Leigh syndrome, which is a rare genetic disorder that affects the brain and spinal cord.
7. LHON (Leber's Hereditary Optic Neuropathy), which is a rare form of vision loss that can lead to blindness in one or both eyes.
8. Mitochondrial DNA mutation, which can cause a wide range of symptoms including seizures, developmental delays, and muscle weakness.
9. Mitochondrial myopathy, encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS)
10. Kearns-Sayre syndrome, which is a rare progressive disorder that affects the nervous system and other organs.

It's important to note that this is not an exhaustive list and there are many more mitochondrial diseases and disorders that can affect individuals. Additionally, while these diseases are rare, they can have a significant impact on the quality of life of those affected and their families.
