Rabbit Anti-Human POLL polyclonal antibody for ELISA, WB. This gene encodes a DNA polymerase. DNA polymerases catalyze DNA-template-directed extension of the 3-end of a DNA strand. This particular polymerase, which is a member of the X family of DNA polymerases, likely plays a role in non-homologous end joining and other DNA repair processes. Alternatively spliced transcript variants have been described. [provided by RefSeq, Mar 2010]
