Product Specific Information

Immunohistochemistry (PFA fixed): incubate antibody for 30 min at room temperature (RT).
Staining of formalin-fixed tissues requires heating tissue sections in 10 mM Tris with 1 mM EDTA, pH 9.0, for 45 min at 95°C, followed by cooling at RT for 20 minutes.

Target Information

Initiation of transcription by RNA polymerase II requires the activities of more than 70 polypeptides. The protein that coordinates these activities is transcription factor IID (TFIID), which binds to the core promoter to position the polymerase properly, serves as the scaffold for assembly of the remainder of the transcription complex, and acts as a channel for regulatory signals.

TFIID is composed of the TATA-binding protein (TBP) and a group of evolutionarily conserved proteins known as TBP-associated factors (TAFs). TAFs may participate in basal transcription, serve as coactivators, function in promoter recognition, or modify general transcription factors (GTFs) to facilitate complex assembly and transcription initiation.

A distinctive feature of TBP is a long string of glutamines in the N-terminal region. This region modulates the DNA binding activity of the C terminus, affecting the rate of transcription complex formation and initiation. Mutations that expand the number of CAG repeats encoding this polyglutamine tract are associated with spinocerebellar ataxia 17, a neurodegenerative disorder classified as a polyglutamine disease.
