Baculovirus-Insect cells
Form/Format
1x Sample Buffer (1x modified RIPA buffer+1x SDS loading buffer).
Modified RIPA Lysis Buffer: 50 mM Tris-HCl pH 7.4, 150 mM NaCl, 1mM EDTA, 1% Triton X-100, 0.1% SDS, 1% Sodium deoxycholate, 1mM PMSF.
Sequence Positions
613aa
Sequence
Leu397-Asn772
Applicable Applications for TLK2 cell lysate
Western Blot (WB)
Application Notes
WB: Use at an assay dependent dilution.
Species
Human
Recommend Usage
1. Centrifuge the tube for a few seconds and ensure the pellet at the bottom of the tube.2. Re-dissolve the pellet using 200uL pure water and boil for 2-5 min.
Sequence Construction
A DNA sequence encoding the amino acids (Leu 397-Asn 772) of human TLK2 (Q86UE8-1) was fused with the N-terminal polyhistidine-tagged GST tag at the N-terminus.
Preparation Method
Cell lysate was prepared by homogenization of the over-expressed cells in ice-cold modified RIPA Lysis Buffer with cocktail of protease inhibitors. Cell debris was removed by centrifugation. Protein concentration was determined by Bradford assay (protein assay, Microplate Standard assay). The cell lysate was boiled for 5 min in 1 x SDS loading buffer (50mM Tris-HCl pH 6.8, 12.5% glycerol, 1% sodium dodecylsulfate, 0.01% bromophenol blue) containing 5% b-mercaptoethanol, and lyophilized.
Preparation and Storage
Store at 4 degree C for up to twelve months from date of receipt. After re-dissolution, aliquot and store at -80 degree C for up to twelve months. Avoid repeated freeze-thaw cycles.
Samples are stable for up to twelve months from date of receipt.
Related Product Information for TLK2 cell lysate
Serine/threonine-protein kinase tousled-like 2, also known as PKU-alpha, Tousled-like kinase 2 and TLK2, is a nucleus protein which belongs to the protein kinase superfamily and Ser/Thr protein kinase family. The tousled-like kinases are an evolutionarily conserved family of proteins implicated in DNA repair, DNA replication and mitosis in metazoans and plants. Their absence from the yeasts and other eukaryotic 'microbes' suggests a specific role for them in the development of multicellular organisms. Tousled-like kinase 2/TLK2 is widely expressed. It is present in fetal placenta, liver, kidney, pancreas, heart and skeletal muscle. It is also found in adult cell lines. Tousled-like kinase 2/TLK2 contains one protein kinase domain. Tousled-like kinase 2/TLK2 is rapidly and transiently inhibited by phosphorylation following the generation of DNA double-stranded breaks during S-phase. This is cell cycle checkpoint and ATM-pathway dependent and appears to regulate processes involved in chromatin assembly.

This Human TLK2 overexpression lysate was created in Baculovirus-Insect cells and intented for use as a Western blot (WB) positive control. Purification of TLK2 protein from the overexpression lysate was verified.

NCBI Description

The Tousled-like kinases, first described in Arabidopsis, are nuclear serine/threonine kinases that are potentially involved in the regulation of chromatin assembly.[supplied by OMIM, Apr 2004]

Uniprot Description

TLK2: Serine/threonine-protein kinase involved in the process of chromatin assembly and probably also DNA replication, transcription, repair, and chromosome segregation. Phosphorylates the chromatin assembly factors ASF1A AND ASF1B. Phosphorylation of ASF1A prevents its proteasome-mediated degradation, thereby enhancing chromatin assembly. Negative regulator of amino acid starvation-induced autophagy. Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. 3 isoforms of the human protein are produced by alternative splicing.

Protein type: Protein kinase, Other; EC 2.7.11.1; Kinase, protein; Protein kinase, Ser/Thr (non-receptor); Other group; TLK family

Chromosomal Location of Human Ortholog: 17q23

Cellular Component: perinuclear region of cytoplasm; intermediate filament; nucleus

Molecular Function: protein serine/threonine kinase activity; protein binding; ATP binding

Biological Process: negative regulation of autophagy; peptidyl-serine phosphorylation; regulation of chromatin assembly or disassembly; chromatin modification; cell cycle; protein amino acid phosphorylation; response to DNA damage stimulus; negative regulation of proteasomal ubiquitin-dependent protein catabolic process; chromosome segregation

Product Notes

The TLK2 tlk2 (Catalog #AAA8114573) is a Cell Lysate produced from Baculovirus-Insect cells and is intended for research purposes only. The product is available for immediate purchase. The immunogen sequence is 613aa. AAA Biotech's TLK2 can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB). WB: Use at an assay dependent dilution. Researchers should empirically determine the suitability of the TLK2 tlk2 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. The amino acid sequence is listed below: Leu397-Asn 772. It is sometimes possible for the material contained within the vial of "TLK2, Cell Lysate" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
