  • 产品描述：

    The POLH antibody (CSB-PA009343LA01HU) is used to recognize the POLH protein only in human samples. It is generated in the rabbit with a peptide mapping within amino acids 408-609 of the human POLH immunized. And it occurs as an unconjugated IgG. Purification by protein G reaches up to 95% in purity. This POLH polyclonal antibody has been validated for use in ELISA, WB, IF, and IHC applications. Its target protein POLH mainly functions to replicate damaged DNA caused especially by ultraviolet (UV) rays from sunlight.

  • 功能：
    DNA polymerase specifically involved in the DNA repair by translesion synthesis (TLS). Due to low processivity on both damaged and normal DNA, cooperates with the heterotetrameric (REV3L, REV7, POLD2 and POLD3) POLZ complex for complete bypass of DNA lesions. Inserts one or 2 nucleotide(s) opposite the lesion, the primer is further extended by the tetrameric POLZ complex. In the case of 1,2-intrastrand d(GpG)-cisplatin cross-link, inserts dCTP opposite the 3' guanine. Particularly important for the repair of UV-induced pyrimidine dimers. Although inserts the correct base, may cause base transitions and transversions depending upon the context. May play a role in hypermutation at immunoglobulin genes. Forms a Schiff base with 5'-deoxyribose phosphate at abasic sites, but does not have any lyase activity, preventing the release of the 5'-deoxyribose phosphate (5'-dRP) residue. This covalent trapping of the enzyme by the 5'-dRP residue inhibits its DNA synthetic activity during base excision repair, thereby avoiding high incidence of mutagenesis. Targets POLI to replication foci.
