Transcription factor II H (TFIIH) complex is recruited to DNA damage sites after the damage is recognized by the XPC:RAD23:CETN2 complex and the UV-DDB complex (DDB1:DDB2) (Volker et al. 2001, Araujo and Wood 1999).

TFIIH consists of ten subunits organized into a ring-like structure (Schultz et al. 2000). The TFIIH core, also forming a ring-like structure, includes a DNA helicase ERCC3 (XPB), GTF2H1 (BTF2-p62), GTF2H2 (BTF2-p44), GTF2H3 (BTF2-p34) and GTF2H4 (BTF2-p52). GTF2H4 directly interacts with ERCC3 and anchors it to the TFIIH complex (Jawhari et al. 2002). Another DNA helicase, ERCC2 (XPD) is anchored to the TFIIH complex by binding to the GTF2H2 subunit (Coin et al. 1998). The CDK-activating kinase (CAK) complex, consisting of CCNH (cyclin H), CDK7 and MNAT1 (MAT1) is included in the TFIIH complex through an interaction with ERCC2 (Reardon et al. 1996, Rossignol et al. 1997). The tenth subunit, GTF2H5 (TTDA, TFB5, BTF2-p5) is important for the stability of the TFIIH complex (Giglia-Mari et al. 2004). The TFIIH complex binds the DNA damage site after XPC:RAD23:CETN2 complex recognizes the damage (Volker et al. 2001, Riedl et al. 2003), and the ERCC3 and GTF2H1 subunits of TFIIH directly interact with XPC (Yokoi et al. 2003).
