Is predicted to encode a protein with the following domains: G-protein beta WD-40 repeat; Transcription initiation factor TFIID subunit 5; WD40/YVTN repeat-like-containing domain superfamily; WD40 associated region in TFIID subunit, NTD2 domain; TFIID subunit TAF5, NTD2 domain; WD40 repeat; LIS1 homology motif; TFIID subunit TAF5, NTD2 domain superfamily; WD domain, G-beta repeat; and WD40-repeat-containing domain superfamily. Is an ortholog of C. elegans taf-5. In C. elegans, taf-5 is involved in embryo development and transcription by RNA polymerase II.
