Protein FULL name:

5' to 3' DNA helicase, involved in nucleotide excision repair and transcription; subunit of RNA polymerase II transcription initiation factor TFIIH; subunit of Nucleotide Excision Repair Factor 3 (NEF3); homolog of human XPD protein

Rad3p (Saccharomyces cerevisiae) is product of expression of RAD3 gene.

Rad3p is involved in:

NER in Saccharomyces cerevisiae

FUNCTION: ATP-dependent DNA helicase involved in excision repair of DNA damaged with UV light, bulky adducts, or cross-linking agents. Necessary for excision of pyrimidine dimers. Also unwinds DNA/RNA duplexes. Plays an essential role in the cell viability. Involved in the maintenance of the fidelity of DNA replication. Acts as component of the general transcription and DNA repair factor IIH (TFIIH) core, which is essential for both basal and activated transcription, and is involved in nucleotide excision repair (NER) of damaged DNA. TFIIH has CTD kinase and DNA- dependent ATPase activity, and is essential for polymerase II transcription in vitro.

CATALYTIC ACTIVITY: ATP + H(2)O = ADP + phosphate.

SUBUNIT: Component of the TFIIH core complex, which is composed of RAD3, SSL1, SSL2, TFB1, TFB2, TFB4 and TFB5.

INTERACTION: Q03290:TFB3; NbExp=1; IntAct=EBI-14762, EBI-31406;


MISCELLANEOUS: Present with 14400 molecules/cell in log phase SD medium.

SIMILARITY: Belongs to the helicase family. RAD3/XPD subfamily.

SIMILARITY: Contains 1 helicase ATP-binding domain.

This protein can be a part of a given complexes:
NCBI GenPept GI number(s): 6321019
Species: Saccharomyces cerevisiae
