Gtf2a1 Gene Summary [Rat]
Predicted to enable several functions, including RNA polymerase II core promoter sequence-specific DNA binding activity; RNA polymerase II general transcription initiation factor activity; and general transcription initiation factor binding activity. Predicted to be involved in positive regulation of transcription initiation by RNA polymerase II and transcription by RNA polymerase II. Predicted to be located in cytosol and nucleoplasm. Predicted to be part of transcription factor TFIIA complex; transcription factor TFIID complex; and transcription preinitiation complex. Orthologous to human GTF2A1 (general transcription factor IIA subunit 1). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Gtf2a1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
