DNA polymerase iota is an enzyme that in humans is encoded by the POLIgene.[4] It is found in higher eukaryotes, and is believed to have arisen from a gene duplication from Pol η. Pol ι, is a Y family polymerase that is involved in translesion synthesis. It can bypass 6-4 pyrimidine adducts and abasic sites and has a high frequency of wrong base incorporation. Like many other Y family polymerases Pol ι, has low processivity, a large DNA binding pocket and doesn't undergo conformational changes when DNA binds. These attributes are what allow Pol ι to carry out its task as a translesion polymerase. Pol ι only uses Hoogsteen base pairing, during DNA synthesis, it will add adenine opposite to thymine in the syn conformation and can add both cytosine and thymine in the anti conformation across guanine, which it flips to the syn conformation.
Poli is the plural of polis. Polis is often translated as city, but there was a very important difference between an ancient Greek polis and a modern city. The ancient Greeks saw themselves as citizens of their poli no matter where they lived. If a person was born in Athens, he would consider himself an Athenian. Poli is a town and comune in Lazio, central Italy. It is located in the Monti Prenestini area. It is also the birthplace of Pope Innocent XIII and Cardinal Agostino Vallini.
