Rabbit anti-Human DNA Polymerase beta Polyclonal Antibody

Uniprot Id

P06746

Target Species

Human

Target Name

POLB

Target Full Name

DNA polymerase beta

Target Function

Repair polymerase that plays a key role in base-excision repair. Has 5'-deoxyribose-5-phosphate lyase (dRP lyase) activity that removes the 5' sugar phosphate and also acts as a DNA polymerase that adds one nucleotide to the 3' end of the arising single-nucleotide gap. Conducts 'gap-filling' DNA synthesis in a stepwise distributive fashion rather than in a processive fashion as for other DNA polymerases.

Target Subcellular Location

Nucleus. Cytoplasm. Note=Cytoplasmic in normal conditions. Translocates to the nucleus following DNA damage.

Target Protein Families

DNA polymerase type-X family

Target Synonyms

DNA directed DNA polymerase beta; DNA pol beta; DNA polymerase beta; DNA polymerase beta subunit; DPOLB_HUMAN; MGC125976; Pol B; Pol beta; POLB; Polymerase (DNA directed) beta

Target Background

The protein encoded by this gene is a DNA polymerase involved in base excision and repair, also called gap-filling DNA synthesis. The encoded protein, acting as a monomer, is normally found in the cytoplasm, but it translocates to the nucleus upon DNA damage. Several transcript variants of this gene exist, but the full-length nature of only one has been described to date.
