GTF2I a multifunctional phosphoprotein with roles in transcription and signal transduction. Interacts with the basal transcription machinery by coordinating the formation of a multiprotein complex at the C-FOS promoter, and linking specific signal responsive activator complexes. Promotes the formation of stable high-order complexes of SRF and Phox1 and interacts cooperatively with Phox1 to promote serum-inducible transcription of a reporter gene driven by the C- FOS serum response element (SRE). Acts as a coregulator for USF1 by binding independently two promoter elements, a pyrimidine-rich initiator (Inr) and an upstream E-box. Its gene is known to contain at least 34 exons. Four splice variant isoforms have been described. Note: This description may include information from UniProtKB.
