__TOC__
 +
== Function ==
 +
'''DNA damage-binding protein''' (DDB) functions in nucleotide excision repair. It prevents UV damage to DNA. <scene name='54/541124/Cv/2'>DDB is a heterodimer composed of the large DDB1 and the smaller DNA-binding DDB2</scene>.
 +
DNA in this complex with DDB1 and DDB2 contains modified compounds <scene name='54/541124/Cv/5'>5PY and 64T</scene> (in darkmagenta and magenta, respectively), they are derivatives from parent compound THYMIDINE-5'-MONOPHOSPHATE.<ref>PMID:18593899</ref><br /> Water molecules shown as red spheres.

== Disease ==
-
 
+
Defective activity of DDB2 causes the repair defects in patients with XPE - an autosomal disorder characterized by early onset of cancer and photosensitivity.
