Major DNA-binding protein (UniProt: P04296) is encoded by DBP (also known as Infected cell protein 8, ICP8, UL29) gene (Gene ID: 2703458) in human herpes simplex virus 1. HSV1-ICP8 is a 128 kDa, single stranded DNA binding protein of the herpesviridae family. It is an essential replication factor for both Herpes Simplex Virus Type 1 (HSV-1) and Adeno-Associated Virus (AAV) DNA replication. It binds tightly and cooperatively to ssDNA and destabilizes dsDNA helices, promotes DNA strand transfer, and renaturation of ssDNA. ICP8 is reported to regulate viral gene expression by repressing transcription from the parental viral genome and stimulating gene expression from the progeny genome. It is known to associate in replication compartments with over 50 cellular and viral proteins-many of which are involved in DNA replication and repair, recombination, and chromatin modeling. In the absence of DNA replication, HSV1-ICP8 is found in the nuclear framework-associated structures (pre-replicative sites); however, as viral DNA replication proceeds, it migrates to globular intranuclear structures (replication compartments).
