Background: Required for DNA repair. Binds to DDB2 to form the UV-damaged DNA-binding protein complex(the UV-DDB complex). The UV-DDB complex may recognize UV-induced DNA damage and recruit proteins of the nucleotide excision repair pathway(the NER pathway) to initiate DNA repair. The UV-DDB complex preferentially binds to cyclobutane pyrimidine dimers(CPD), 6-4 photoproducts(6-4 PP), apurinic sites and short mismatches. Also appears to function as a component of numerous distinct DCX(DDB1-CUL4-X-box) E3 ubiquitin-protein ligase complexes which mediate the ubiquitination and subsequent proteasomal degradation of target proteins. The functional specificity of the DCX E3 ubiquitin-protein ligase complex is determined by the variable substrate recognition component recruited by DDB1. DCX(DDB2)(also known as DDB1-CUL4-ROC1, CUL4-DDB-ROC1 and CUL4-DDB-RBX1) may ubiquitinate histone H2A, histone H3 and histone H4 at sites of UV-induced DNA damage. The ubiquitination of histones may facilitate their removal from the nucleosome and promote subsequent DNA repair. DCX(DDB2) also ubiquitinates XPC, which may enhance DNA-binding by XPC and promote NER. DCX(DTL) plays a role in PCNA-dependent polyubiquitination of CDT1 and MDM2-dependent ubiquitination of TP53 in response to radiation-induced DNA damage and during DNA replication. DCX(ERCC8)(the CSA complex) plays a role in transcription-coupled repair(TCR). May also play a role in ubiquitination of CDKN1B

The Universal Fit-Neptune 0.5–10 µL XL pipette tips are extra-long tips made from pure polypropylene for accurate handling of very small liquid volumes. They are built to fit most common pipette brands and deliver precise transfer between 0.5 and 10 microliters. The XL length allows access to deep or narrow tubes without contamination from contact with the tube walls. The inner surface is very smooth to prevent liquid from sticking inside the tip, which helps reduce sample loss. These tips are available with or without aerosol barriers and come in sterile or non-sterile formats. Sterile tips are certified free of RNase, DNase, pyrogens, and ATP. They can be autoclaved without melting or warping. The tips come in rack, bulk, or reload packaging and are designed for consistent fit and secure sealing on most pipettes.
