Recombinant Human A3H protein (ab165769)

ARP10 belongs to the cytidine and deoxycytidylate deaminase family. It is a poorly expressed deaminase that is ineffective at inhibiting retroviral replication. ARP10 has DNA deaminase (cytidine deaminase) activity but is not able to mediate G-to-A hypermutation in newly synthesized retroviral DNA. It is present at low level in 293T cells. It is considered an unstable protein, suggesting that it may be degraded by the proteasome (at protein level). Weakly expressed in testis, ovary, fetal liver and skin. There are two named isoforms. ARP10 from old world monkeys has retained its antiviral activity, while it is lost in other primates. It is one of seven related genes or pseudogenes found in a cluster, thought to result from gene duplication, on chromosome 22.
