General annotation (Comments)
| Function | DNA helicase involved in cellular proliferation. Possesses DNA-dependent ATPase and helicase activities. This helicase translocates on single-stranded DNA in the 5' to 3' direction in the presence of ATP and, to a lesser extent, dATP. Its unwinding activity requires a 5'-single-stranded region for helicase loading, since flush-ended duplex structures do not support unwinding. The helicase activity is capable of displacing duplex regions up to 100 bp, which can be extended to 500 bp by RPA or the cohesion establishment factor, the Ctf18-RFC (replication factor C) complex activities. Stimulates the flap endonuclease activity of FEN1. Required for normal sister chromatid cohesion. Required for recruitment of bovine papillomavirus type 1 regulatory protein E2 to mitotic chrmosomes and for viral genome maintenance. Required for maintaining the chromosome segregation and is essential for embryonic development and the prevention of aneuploidy. May function during either S, G2, or M phase of the cell cycle. Binds to both single- and double-stranded DNA. Ref.2 Ref.5 Ref.6 Ref.7 Ref.8 |
| Catalytic activity | ATP + H2O = ADP + phosphate. Ref.5 |
| Cofactor | Binds 1 4Fe-4S cluster By similarity. |
| Enzyme regulation | Helicase shows maximal activity with magnesium ions at low concentrations (0.5-1mM) whereas is markedly inhibited at higher levels (5 mM and above). Stimulated by 25-50 mM potassium acetate, stimulated to a lesser extent by 25 mM of ammonium acetate, and markedly inhibited by sodium acetate. The ATPase activity is stimulated by high salt levels (up to a 0.1 M) and potassium salts (glutamate, chloride or acetate) are more effective than the corresponding sodium salts. Ref.8 |
| Subunit structure | Interacts with the CTF18-RFC complex, PCNA and FEN1. Forms a complex with RAD21, SMC1 and SMC3. Interacts with bovine papillomavirus type 1 regulatory protein E2. Ref.7 Ref.8 |
| Subcellular location | Nucleus. Nucleus › nucleolus. Note: During the early stages of mitosis, localizes to condensed chromatin and is released from the chromatin with progression to metaphase. Also localizes to the spindle poles throughout mitosis and at the midbody at later stages of mitosis (metaphase to telophase). Co-localizes with bovine papillomavirus type 1 regulatory protein E2 at early stages of mitosis. Ref.6 |
| Tissue specificity | Highly expressed in spleen, B-cells, thymus, testis, ovary, small intestine, and pancreas. Very low expression seen in the brain. Expressed in dividing cells and/or cells undergoing high levels of recombination. No expression is seen in cells signaled to terminally differentiate. Expressed in keratinocyte growth factor-stimulated cells but not in serum, EGF and IL1-beta-treated keratinocytes. Ref.1 Ref.2 |
| Involvement in disease | Warsaw breakage syndrome (WBRS) [MIM:613398]: A syndrome characterized by severe microcephaly, pre- and postnatal growth retardation, facial dysmorphism and abnormal skin pigmentation. Additional features include high arched palate, coloboma of the right optic disk, deafness, ventricular septal defect, toes and fingers abnormalities. At cellular level, drug-induced chromosomal breakage, a feature of Fanconi anemia, and sister chromatid cohesion defects, a feature of Roberts syndrome, coexist. |
| Sequence similarities | Belongs to the DEAD box helicase family. DEAH subfamily. DDX11/CHL1 sub-subfamily. Contains 1 helicase ATP-binding domain. |
| Sequence caution | The sequence CAA67895.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence CAA67895.1 differs from that shown. Reason: Frameshift at positions 644 and 648. |
