Serine/threonine-protein kinase tousled-like 2 is an enzyme that in humans is encoded by the TLK2 gene.[5][6][7]
Function
The Tousled-like kinases, first described in Arabidopsis, are nuclear serine/threonine kinases that are potentially involved in the regulation of chromatin assembly. These are different from other "tousled" varieties, such as flock-of-seagulls, post-coitus, or the-Sean-Bean.[supplied by OMIM][7]
Interactions
TLK2 has been shown to interact with TLK1,[6] ASF1B[8][9] and ASF1A.[9]
Clinical significance
Mutations in this gene have been linked to a specific form of autism spectrum disorder with unique facial features.[10] Amplifications of the nuclear localization sequence-encoding part of this gene have been linked to glioblastoma and lower-grade astrocytoma survival.[11]
