function:May play a role in nucleotide excision repair (NER) and RNA polymerase II (POL II) transcription by interacting with ERCC2/XPD and ERCC3/XPB helicases, both subunits of NER-transcription factor TFIIH. May also function as a transcriptional coactivator of estrogen receptor (ER). May be involved in regulation of ER activity by bridging TFIIH with ER or may facilitate TFIIH-mediated phosphorylation of ER in specific promoters and cell types.,similarity:Belongs to the MET18/MMS19 family.,similarity:Contains 7 HEAT repeats.,subunit:Interacts with ERCC2/XPD, ERCC3/XPB and NCOA3/RAC3.,tissue specificity:Ubiquitously expressed with higher expression in testis.,
Nucleus . Cytoplasm, cytoskeleton, spindle . Cytoplasm, cytoskeleton, microtubule organizing center, centrosome . In mitosis, enriched on centrosomes during prophase, localizes to the spindle during metaphase and surrounds compacted spindle midzone microtubules during telophase. .
Ubiquitously expressed with higher expression in testis.
