Description
Product Characteristics:
TLK1 is a nuclear serine/threonine kinases that are potentially involved in the regulation of chromatin assembly. TLK1 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. Isoform 3 phosphorylates and enhances the stability of the t-SNARE SNAP23, augmenting its assembly with syntaxin.
Subcellular location: Nucleus
Synonyms: PKU beta, serine threonine protein kinase, Serine/threonine protein kinase tousled like 1, TLK1, Tousled like kinase 1.
Target Information: The protein encoded by this gene is a serine/threonine kinase that may be involved in the regulation of chromatin assembly. The encoded protein is only active when it is phosphorylated, and this phosphorylation is cell cycle-dependent, with the maximal activity of this protein coming during S phase. The catalytic activity of this protein is diminished by DNA damage and by blockage of DNA replication. Three transcript variants encoding different isoforms have been found for this gene.
