Tbp Protein Tata Box Binding Protein is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
TBP (TATA-Box Binding Protein) is a general transcription factor that initiates RNA polymerase II transcription by binding to the TATA box promoter element. It is encoded by the TBP gene located on chromosome 6q27 and is essential for eukaryotic transcription. [1]
