APOBEC3B also known as Apolipoprotein B mRNA editing enzyme catalytic subunit 3B is a protein that plays a role in DNA cytosine deamination. It selectively deaminates cytosine bases in DNA to uracil resulting in mutations. The protein has a molecular mass of approximately 46 kDa. APOBEC3B expression occurs primarily in the liver and testes but it can also be detected in other tissues.
Biological function summary
APOBEC3B functions as part of the innate immune defense by restricting viral replication through inducing hypermutation in viral genomes. It does not form a stable complex but can act in conjunction with other APOBEC3 family members. APOBEC3B activity is critical in the context of host-virus interactions especially in the defense against retroviruses and other viruses.
Pathways
Scientists classify APOBEC3B within the viral restriction and DNA damage response pathways. In these pathways the protein works alongside other DNA repair proteins such as AID (Activation-Induced cytidine Deaminase). APOBEC3B participates in editing events that provide insights into virus-host co-evolution and resilience against viral infections.
Researchers have linked APOBEC3B to cancer development due to its ability to induce genetic mutations. Its mutagenic activity connects it with a variety of cancers including breast cancer and head and neck cancer. Through these diseases the protein shows functional connections to other DNA mutators and repair proteins that it affects or interacts with during tumorigenesis.
