TLK2 (Q86UE8) - Overview - Molecular Target Synopsis


TLK2, Serine/threonine-protein kinase tousled-like 2
Enzyme Classification
UniProt Q86UE8

Also Known as TLK2_HUMAN, 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. Monomer and heterodimer with TLK1. Interacts with ASF1A and ASF1B. Association with 14-3-3 proteins such as YWHAZ regulates subcellular location. May also interact with FEZ1/LZTS1 and FEZ2.
