Processes
aging / base-excision repair / base-excision repair, gap-filling / cellular response to DNA damage stimulus / DNA repair / DNA-dependent DNA replication / homeostasis of number of cells / immunoglobulin heavy chain V-D-J recombination / inflammatory response / intrinsic apoptotic signaling pathway in response to DNA damage / lymph node development / neuron apoptotic process / pyrimidine dimer repair / response to ethanol / response to gamma radiation / response to hyperoxia / salivary gland morphogenesis / somatic hypermutation of immunoglobulin genes / spleen development
Components

General Function
Microtubule binding
Specific 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.
