General annotation (Comments)
| Function | 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. Isoform 3 protects the cells from the ionizing radiation by facilitating the repair of DSBs. In vitro, phosphorylates histone H3 at 'Ser-10'. Ref.1 Ref.2 Ref.3 Ref.9 Ref.10 Ref.11 |
| Catalytic activity | |
| Cofactor | |
| Enzyme regulation | Cell-cycle regulated, maximal activity in S-phase. Inactivated by phosphorylation at Ser-743, potentially by CHEK1. Ref.2 Ref.11 |
| Subunit structure | Heterodimerizes with TLK2. Interacts with ASF1A and ASF1B. Ref.2 Ref.9 |
| Subcellular location | |
| Tissue specificity | Widely expressed. Present in fetal placenta, liver, kidney and pancreas but not heart or skeletal muscle. Also found in adult cell lines. Isoform 3 is ubiquitously expressed in all tissues examined. Ref.1 Ref.3 |
| Sequence similarities | Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. Contains 1 protein kinase domain. |
| Sequence caution | The sequence AAF03094.1 differs from that shown. Reason: Erroneous initiation. The sequence BAA09486.2 differs from that shown. Reason: Erroneous initiation. |
