  Figure 2. hHus1 and hRad1 associate with each other prior to forming the 9-1-1 complex with Rad9. In response to DNA damage and replication block, the 9-1-1 complex is loaded into DNA by Rad17/RFC clamp loader and acts as checkpoint sensor to activate ATM (ataxia telangiectasia [AT] mutated protein) or ATR (ATM- and Rad3-related protein) protein kinase. The 9-1-1 complex interacts with and stimulates many DNA repair enzymes involved in base excision repair (BER), nucleotide excision repair (NER), and mismatch repair (MMR). The damage recognition repair enzymes may serve as adaptors to signal DNA damage responses including enhanced DNA repair, cell cycle arrest, and apoptosis.
Description Amino acids: 280. Molecular weight: 31.7 kDa. Hus1 is a component of the 9-1-1 cell cycle checkpoint complex that plays a critical role in sensing DNA damage and maintaining genomic stability.
Expression Found in all tissues.
Localisation Nucleus and cytoplasm. In discrete nuclear foci upon DNA damage.
Function Hus1 along with and Rad1 forms the 9-1-1 complex (Hang and Lieberman, 2000; St Onge et al., 1999; Volkmer and Karnitz, 1999). Hus1 and Rad1 can also form a stable 1:1 complex (Doré et al., 2009; Sohn and Cho, 2009; Xu et al., 2009). The 9-1-complex is loaded onto the DNA by a specific clamp loader (Rad17-RFC2-RFC3-RFC4-RFC5) in response to many different genotoxic stresses (alkylation, oxidation, ultraviolet light radiation and ionizing radiation), and replication inhibitors (Bermudez et al., 2003; Ellison and Stillman, 2003). The Rad1-Rad9 interface may be opened to encircle DNA (Doré et al., 2009; Sohn and Cho, 2009; Xu et al., 2009).

The structure of the 9-1-1 complex (Doré et al., 2009; Sohn and Cho, 2009; Xu et al., 2009) is similar to the sliding clamp proliferating cell nuclear antigen protein (PCNA) (Gulbis et al., 1996; Krishna et al., 1994). Hus1 interacts with Rad9 and Rad1 through its N terminal domain and C terminal domain, respectively. The structure and surface charge distribution of the interdomain connecting loop (IDCL) of Hus1 differs from those of other two subunits (Doré et al., 2009; Sohn and Cho, 2009; Xu et al., 2009). The IDCL of Hus1 contains an N-terminal alpha helix and positive charge cluster. These differences among Hus1, Rad9, and Rad1 may contribute to different binding affinities to their partner proteins. For example, MutY homolog (MYH) has a strong preference to bind Hus1 (Chang and Lu, 2005; Shi et al., 2006).

Recent structural and functional analyses indicate that the Hus1 binding region of MYH adopts a stabilized conformation projecting away from the catalytic domain to form a docking scaffold for Hus1 and binds to Hus1 through electrostatic interaction (Luncsford et al., 2010).

The 9-1-1 complex is required to activate two checkpoint sensors-ATM (ataxia telangiectasia [AT] mutated protein) and ATR (ATM- and Rad3-related protein), which are phosphoinositol phosphate 3 kinase-related kinases (PIKKs) (Zhou and Elledge, 2000). The DNA-bound 9-1-1 complex facilitates ATM- or ATR-mediated phosphorylation of more than 700 proteins including Chk1, Chk2, p53, and BRCA1 (Zhou and Elledge, 2000). Hus1 facilitated phosphorylation of Chk1 kinase is required for the ATR-dependent checkpoint; and regulates S-phase progression, G2/M arrest, and replication fork stabilization (Sancar et al., 2004; Sancar et al., 2004). However, Hus1 is not required for Chk2 phosphorylation in response to certain genotoxins (Weiss et al., 2003).

Besides acting as a DNA damage sensor, the 9-1-1 complex plays an integral role in several DNA repair pathways including base excision repair (BER), mismatch repair (MMR), and nucleotide excision repair (NER) (see figure 2) (Helt et al., 2005).

In the BER pathway, the 9-1-1 complex facilitates and interacts with several DNA glycosylases including MYH (Chang and Lu, 2005; Shi et al., 2006; Chang and Lu, 2005; Shi et al., 2006), 8-oxoG glycosylase (OGG1) (Park et al., 2009), NEIL1 (Guan et al., 2007a), and thymine DNA glycosylase (TDG) (Guan et al., 2007b). The 9-1-1 complex also interacts with and stimulates other BER enzymes including APE1 (Gembka et al., 2007), POLbeta (Toueille et al., 2004), FEN1 (Friedrich-Heineken et al., 2005; Wang et al., 2004a), RPA (Wu et al., 2005), and DNA ligase 1 (Smirnova et al., 2005; Wang et al., 2006a). Thus, the 9-1-1 complex may provide a platform for the assembly and function of the BER machinery (Balakrishnan et al., 2009; Lu et al., 2006). The 9-1-1 complex enhances mismatch repair via direct interaction with mismatch recognition proteins (MSH2/MSH3, MSH2/MSH6, and MLH1/PMS2) (Bai et al., 2010; He et al., 2008). Hus1 interacts with MSH2/MSH3 and MSH2/MSH6, but not with MLH1/PMS2 (Bai et al., 2010; He et al., 2008).

In the NER pathway, interactions between Saccharomyces cerevisiae Rad14 (hXPA homolog) and the checkpoint proteins ScDdc1 (hRad9 homolog) and ScMec3 (hHus1 homolog) have been demonstrated (Giannattasio et al., 2004). Inactivation of NER by knock down of XPA and XPC resulted in a decrease of G1 phase cells that displayed Rad9 foci in response to UV light (Warmerdam et al., 2009). UV light-induced Rad9 foci also colocalized with TopBP1 and gamma-H2AX (Warmerdam et al., 2009).

Hus1 interacts with histone deacetylase HDAC1 (Cai et al., 2000). A novel pathway has been proposed that HDAC1 is involved in G(2)/M checkpoint control through the interaction with the 9-1-1 complex.

Jab1 physically associates with the 9-1-1 complex, causes the translocation of the 9-1-1 complex from the nucleus to the cytoplasm, and mediates the rapid degradation of the 9-1-1 complex (Huang et al., 2007).

Homology hHus1 homologues from many eukaryotes are highly conserved. The following diagram shows the sequence alignment of human Hus1 with Hus1 of fission yeast Schizosaccharomyces pombe. The N-terminal domain of Hus1 is structurally similar to the C-terminal domain. The structure of Hus1 (Doré et al., 2009; Sohn and Cho, 2009; Xu et al., 2009) is similar to those of Rad9, Rad1, and PCNA (Gulbis et al., 1996; Krishna et al., 1994).


Note Complete inactivation of the mouse Hus1 results in chromosomal instability, genotoxin hypersensitivity, and embryonic lethality.

Implicated in

Entity Breast cancer
Note Hus1 inactivation in the mammary epithelium resulted in genome damage that induced apoptosis and led to depletion of Hus1-null cells from the mammary gland. Dual inactivation of Hus1 and p53 in the mouse mammary gland results in accumulation of damaged cells and impaired tissue regeneration (Yazinski et al., 2009).
Oncogenesis Single nucleotide polymorphism (SNP) analysis supports the potential role of Hus1 in sporadic breast cancer (Vega et al., 2009). SNPs in hHUS1 at chromosome 7 base pair positions 47778020 (C) and 47789957 (G) are statistically associated with breast cancer development (Vega et al., 2009).
Entity Ovarian tumors
Oncogenesis Hus1 expression levels correlate significantly with the clinicopathologic factors of bad prognosis of ovarian tumors (de la Torre et al., 2008).
Entity Cancer therapy
Note The status of Hus1 can influence response to cancer therapy. Down-regulation of hHus1 by antisense RNA enhances the sensitivity of human lung carcinoma cells to cisplatin (a DNA cross-linker), presumably by enhancing apoptosis (Kinzel et al., 2002).
Entity Genomic stability
Note Inactivation of mouse or human Hus1 results in impaired DNA damage signaling and severe spontaneous chromosomal instability (Weiss et al., 2002; Weiss et al., 2000; Kinzel et al., 2002).
Entity Drug sensitivity
Note Cells lacking Hus1 are hypersensitive to certain genotoxins including camptothecin (CPT), hydroxyurea (HU), ultraviolet (UV), and ionizing radiation (IR) (Weiss et al., 2000; Wang et al., 2004b; Wang et al., 2006b). Loss of Hus1 sensitizes the cells to etoposide-induced apoptosis by inducing Bim and Puma expressions and releasing Rad9 into the cytosol (Levitt et al., 2005; Levitt et al., 2007; Meyerkord et al., 2008). The role of Hus1 affecting the sensitivity of cells to IR-induced killing is independent of nonhomologous end-joining (NHEJ) but might be linked to homologous recombination repair (HRR) (Wang et al., 2006b).
Entity Development
Note Targeted deletion of mouse Hus1 results in embryonic lethality (Weiss et al., 2000).
Entity Telomere maintenance
Note Severe telomere shortening has been observed in both Hus1-deficient mouse embryonic fibroblasts and thymocytes from conditional Hus1-knockout mice (Francia et al., 2006).
Entity HIV infection (AIDS)
Note Hus1 is required for Human Immunodeficiency Virus type 1 Vpr-mediated G2 cell cycle arrest (Zimmerman et al., 2004).
