Ssl1p |
Protein FULL name:
Component of the core form of RNA polymerase transcription factor TFIIH, which has both protein kinase and DNA-dependent ATPase/helicase activities and is essential for transcription and nucleotide excision repair; interacts with Tfb4p
Ssl1p (Saccharomyces cerevisiae) is product of expression of SSL1 gene.
FUNCTION: 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. SSL1 is essential for translation initiation.
SUBUNIT: Component of the TFIIH core complex, which is composed of RAD3, SSL1, SSL2, TFB1, TFB2, TFB4 and TFB5.
SUBCELLULAR LOCATION: Nucleus (Potential).
MISCELLANEOUS: Present with 2340 molecules/cell in log phase SD medium.
SIMILARITY: Belongs to the GTF2H2 family.
SIMILARITY: Contains 1 VWFA domain.
