'''CRYSTAL STRUCTURE OF HERPES SIMPLEX UL42 BOUND TO THE C-TERMINUS OF HSV POL'''<br />


==Overview==
==CRYSTAL STRUCTURE OF HERPES SIMPLEX UL42 BOUND TO THE C-TERMINUS OF HSV POL==
Herpes simplex virus DNA polymerase is a heterodimer composed of a, catalytic subunit, Pol, and an unusual processivity subunit, UL42, which, unlike processivity factors such as PCNA, directly binds DNA. The crystal, structure of a complex of the C-terminal 36 residues of Pol bound to, residues 1-319 of UL42 reveals remarkable similarities between UL42 and, PCNA despite contrasting biochemical properties and lack of sequence, homology. Moreover, the Pol-UL42 interaction resembles the interaction, between the cell cycle regulator p21 and PCNA. The structure and previous, data suggest that the UL42 monomer interacts with DNA quite differently, than does multimeric toroidal PCNA. The details of the structure lead to a, model for the mechanism of UL42, provide the basis for drug design, and, allow modeling of other proteins that lack sequence homology with UL42 or, PCNA.

== Function ==
[[Category: DNA-directed DNA polymerase]]
[https://www.uniprot.org/uniprot/PAP_HHV11 PAP_HHV11] Plays an essential role in viral DNA replication by acting as the polymerase accessory subunit. Associates with the viral polymerase to increase its processivity and forms high-affinity direct interactions with DNA. Facilitates the origin-binding protein UL9 loading onto DNA thus increasing its ability to assemble into a functional complex capable of unwinding duplex DNA.<ref>PMID:2173776</ref>
