Storage

Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at –20°C. Do not aliquot the antibody.

Specificity / Sensitivity

Phospho-TLK1 (Ser743) Antibody detects endogenous levels of TLK1 only when phosphorylated at serine 743.

Species Reactivity:

Human, Mouse, Rat

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser743 of human TLK1. Antibodies are purified by protein A and peptide affinity chromatography.

Background

Tousled-like kinases (TLK1 and TLK2) are nuclear serine/threonine kinases named for their homology to the Tousled gene from Arabidopsis thaliana, essential for flower development (1). The kinase activities of the TLKs are cell cycle regulated, with maximal activity during S phase (1). TLK appears to play a role in chromatin assembly and DNA damage checkpoint regulation (1,2). In C. elegans, TLK1 is essential for appropriate transcription during embryonic development (3). Substrates for TLK include the human chromatin assembly factor Asf, which functions in DNA replication- and repair-coupled chromatin assembly (2). DNA damage during S phase, when TLK is maximally active, leads to inhibition of TLK activity (1). This inhibition requires ataxia mutated kinase (ATM) and Chk1 (4,5). ATM and the related kinase ATR are activited by DNA damage during S phase, phosphorylate Chk1/Chk2, and block the transition into mitosis (6). Chk1 phosphorylates TLK1 on Ser743 in vitro and in vivo, leading to inhibition of TLK1 activity (4). This process likely provides a mechanism to slow the chromatin assembly processes controlled by TLK in the event of DNA damage.

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
