Description

The first step in producing the recombinant Human TTBK2 protein is to construct a plasmid that encodes the Human TTBK2 protein (18-287aa). The next is to transform this plasmid into e.coli cells, select positive e.coli cells, from which positive cells can be screened and cultured to express the protein. A N-terminal 10xHis tag and C-terminal Myc tag is fused to the protein. The recombinant Human TTBK2 protein is purified through affinity purification from the cell lysate. Its purity is greater than 85%, determined by the SDS-PAGE analysis.

Target Background

Function
Serine/threonine kinase that acts as a key regulator of ciliogenesis: controls the initiation of ciliogenesis by binding to the distal end of the basal body and promoting the removal of CCP110, which caps the mother centriole, leading to the recruitment of IFT proteins, which build the ciliary axoneme. Has some substrate preference for proteins that are already phosphorylated on a Tyr residue at the +2 position relative to the phosphorylation site. Able to phosphorylate tau on serines in vitro.
Gene References into Functions
  1. Enhanced expression of circ-TTBK2 promoted cell proliferation, migration, and invasion, while inhibited apoptosis in glioma cells. PMID: 28219405
  2. TTBK2 down-regulates GluK2 activity by decreasing the receptor protein abundance in the cell membrane via RAB5-dependent endocytosis. PMID: 27607061
  3. TTBK2 is a multifunctional kinase involved in important cellular processes and demands augmented efforts in investigating its functions PMID: 25950000
  4. TTBK2 phosphorylates KIF2A and antagonizes KIF2A-induced depolymerization at microtubules plus ends for cell migration. PMID: 26323690
  5. TTBK2 bound EB1 and Cep164 through its SxIP motifs and a proline-rich motif, respectively. PMID: 25297623
  6. data suggest that TTBK2 also acts upstream of Cep164, contributing to the assembly of distal appendages PMID: 24982133
  7. Dominant truncating mutations in human TTBK2 cause spinocerebellar ataxia type 11 (SCA11); these mutant proteins do not promote ciliogenesis and inhibit ciliogenesis in wild-type cells. PMID: 23141541
  8. TTBK2 is a completely novel regulator of Na(+)-coupled glucose transport. PMID: 22814243
  9. findings reveals a major role of PRKX, TTBK2 and RSK4 in triggering Sunitinib resistance formation; data suggest transcriptional regulation of these kinases together with other proteins might play an important role in formation of Sunitinib resistance by affecting transcription factors PMID: 22020623
  10. two-basepair deletion (c.1306_1307delGA, p.D435fs448X in exon 12) lead to a premature stop codon in the TTBK2 gene; spinocerebellar ataxia patients had phenotypic of slowly progressive almost pure cerebellar ataxia with normal life expectancy PMID: 20667868
  11. Examination the TTBK2 gene in 68 unrelated spinocerebellar ataxia patients displayed the normal elution profile, which denoted that no disease-related mutation was identified. We provided the evidence that SCA11 is a rare form of ataxia in China. PMID: 19768375
  12. These data suggest that TTBK2 is important in the tau cascade and in spinocerebellar degeneration. PMID: 18037885
  13. that SCA11 is an extremely rare cause for dominantly inherited ataxias (TTBK2) in the German population. PMID: 19533200
