[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>

[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>

[https://www.uniprot.org/uniprot/MAT1_HUMAN MAT1_HUMAN] Stabilizes the cyclin H-CDK7 complex to form a functional CDK-activating kinase (CAK) enzymatic complex. CAK activates the cyclin-associated kinases CDK1, CDK2, CDK4 and CDK6 by threonine phosphorylation. CAK complexed to the core-TFIIH basal transcription factor activates RNA polymerase II by serine phosphorylation of the repetitive C-terminus domain (CTD) of its large subunit (POLR2A), allowing its escape from the promoter and elongation of the transcripts. Involved in cell cycle control and in RNA transcription by RNA polymerase II.<ref>PMID:10024882</ref>
