    Summary
    Enables transcription coregulator activity. Contributes to TBP-class protein binding activity. Involved in RNA polymerase II preinitiation complex assembly. Part of transcription factor TFIIA complex. Orthologous to several human genes including GTF2A1 (general transcription factor IIA subunit 1). [provided by Alliance of Genome Resources, Dec 2024]
