== Disease ==

[https://www.uniprot.org/uniprot/TBP_HUMAN TBP_HUMAN] Defects in TBP are the cause of spinocerebellar ataxia type 17 (SCA17) [MIM:[https://omim.org/entry/607136 607136]. Spinocerebellar ataxia is a clinically and genetically heterogeneous group of cerebellar disorders. Patients show progressive incoordination of gait and often poor coordination of hands, speech and eye movements, due to degeneration of the cerebellum with variable involvement of the brainstem and spinal cord. SCA17 is an autosomal dominant cerebellar ataxia (ADCA) characterized by widespread cerebral and cerebellar atrophy, dementia and extrapyramidal signs. The molecular defect in SCA17 is the expansion of a CAG repeat in the coding region of TBP. Longer expansions result in earlier onset and more severe clinical manifestations of the disease.<ref>PMID:11313753</ref> <ref>PMID:11448935</ref> <ref>PMID:11939898</ref>

== Function ==
 +
[https://www.uniprot.org/uniprot/TBP_HUMAN TBP_HUMAN] General transcription factor that functions at the core of the DNA-binding multiprotein factor TFIID. Binding of TFIID to the TATA box is the initial transcriptional step of the pre-initiation complex (PIC), playing a role in the activation of eukaryotic genes transcribed by RNA polymerase II. Component of the transcription factor SL1/TIF-IB complex, which is involved in the assembly of the PIC (preinitiation complex) during RNA polymerase I-dependent transcription. The rate of PIC formation probably is primarily dependent on the rate of association of SL1 with the rDNA promoter. SL1 is involved in stabilization of nucleolar transcription factor 1/UBTF on rDNA.<ref>PMID:15970593</ref>

==Overview==

== References ==

The crystal structure of a complex of human TATA-binding protein with TATA-sequence DNA has been solved, complementing earlier TBP/DNA analyses from Saccharomyces cerevisiae and Arabidopsis thaliana. Special insight into TATA box specificity is provided by considering the TBP/DNA complex, not as a protein molecule with bound DNA, but as a DNA duplex with a particularly large minor groove ligand. This point of view provides explanations for: (1) why T.A base-pairs are required rather than C.G; (2) why an alternation of T and A bases is needed; (3) how TBP recognizes the upstream and downstream ends of the TATA box in order to bind properly; and (4) why the second half of the TATA box can be more variable than the first.
