补充说明
- First try to dissolve a small amount of peptide in either water or buffer. The more charged residues on a peptide, the more soluble it is in aqueous solutions.
- If the peptide doesn’t dissolve try an organic solvent e.g. DMSO, then dilute using water or buffer.
- Consider that any solvent used must be compatible with your assay. If a peptide does not dissolve and you need to recover it, lyophilise to remove the solvent.
- Gentle warming and sonication can effectively aid peptide solubilisation. If the solution is cloudy or has gelled the peptide may be in suspension rather than solubilised.
- Peptides containing cysteine are easily oxidised, so should be prepared in solution just prior to use. -

功能
DNA polymerase specifically involved in DNA repair. Plays an important role in translesion synthesis, where the normal high fidelity DNA polymerases cannot proceed and DNA synthesis stalls. Plays an important role in the repair of UV-induced pyrimidine dimers. Depending on the context, it inserts the correct base, but causes frequent base transitions and transversions. May play a role in hypermutation at immunoglobulin genes. Forms a Schiff base with 5'-deoxyribose phosphate at abasic sites, but does not have lyase activity. Targets POLI to replication foci. -
疾病相关
Defects in POLH are the cause of xeroderma pigmentosum variant type (XPV) [MIM:278750]; also designated as XP-V. Xeroderma pigmentosum (XP) is an autosomal recessive disease due to deficient nucleotide excision repair. It is characterized by hypersensitivity of the skin to sunlight, followed by high incidence of skin cancer and frequent neurologic abnormalities. XPV shows normal nucleotide excision repair, but an exaggerated delay in recovery of replicative DNA synthesis. Most XPV patients do not develop clinical symptoms and skin neoplasias until a later age. Clinical manifestations are limited to photo-induced deterioration of the skin and eyes. -
序列相似性
Belongs to the DNA polymerase type-Y family.
Contains 1 umuC domain. -
结构域
The catalytic core consists of fingers, palm and thumb subdomains, but the fingers and thumb subdomains are much smaller than in high-fidelity polymerases; residues from five sequence motifs of the Y-family cluster around an active site cleft that can accommodate DNA and nucleotide substrates with relaxed geometric constraints, with consequently higher rates of misincorporation and low processivity. -
细胞定位

Developed using the ECL technique.
Performed under reducing conditions.
Exposure time: 20 minutes60% confluent 6cm dish of each cell type was washed in PBS then scraped into 150µl of SDS-PAGE buffer, boiled for 5 minutes then sonicated for 10 minutes. 20µl of each sample was loaded in triplicate on a 6.5% polyacrylamide denaturing gel, then transferred to nitrocellulose. The membrane was blocked in 5% non-fat milk in PBS plus 0.1% Tween20 for 30 minutes. The primary antibody, ab17725, was incubated with the membrane in PBS plus 0.1% Tween20 and 5% milk overnight. Where the immunizing peptide was used, 5µl of the peptide was incubated with 5µl of antibody for ten minutes prior to dilution in 2ml of 5% milk in PBS plus 0.1% Tween20, which was then incubated with the blocked membrane overnight.
