General annotation (Comments)
| Function | Atypical tyrosine-protein kinase that plays a central role in chromatin remodeling and acts as a transcription regulator. Involved in DNA damage response by phosphorylating 'Tyr-142' of histone H2AX (H2AXY142ph). H2AXY142ph plays a central role in DNA repair and acts as a mark that distinguishes between apoptotic and repair responses to genotoxic stress. Essential component of the WICH complex, a chromatin remodeling complex that mobilizes nucleosomes and reconfigures irregular chromatin to a regular nucleosomal array structure. The WICH complex regulates the transcription of various genes, has a role in RNA polymerase I and RNA polymerase III transcription, mediates the histone H2AX phosphorylation at 'Tyr-142', and is involved in the maintenance of chromatin structures during DNA replication processes. In the complex, it mediates the recruitment of the WICH complex to replication foci during DNA replication. Also involved in vitamin D-coupled transcription regulation via its association with the WINAC complex, a chromatin-remodeling complex recruited by vitamin D receptor (VDR), which is required for the ligand-bound VDR-mediated transrepression of the CYP27B1 gene. In the WINAC complex, plays an essential role by targeting the complex to acetylated histones, an essential step for VDR-promoter association By similarity. Ref.6 |

Component of the WINAC complex, at least composed of SMARCA2, SMARCA4, SMARCB1, SMARCC1, SMARCC2, SMARCD1, SMARCE1, ACTL6A, BAZ1B/WSTF, ARID1A, SUPT16H, CHAF1A and TOP2B. Interacts with VDR; in a ligand-dependent manner. Interacts with PCNA; the interaction is direct By similarity. Ref.6 Ref.10 |
| Subcellular location | Nucleus By similarity. Note: Accumulates in pericentromeric heterochromatin during replication. Targeted to replication foci throughout S phase via its association with PCNA By similarity. |
| Tissue specificity | Expressed in all tissues examined including heart, brain, spleen, lung, skeletal muscle, kidney and testis. Ref.5 |
| Developmental stage | Expressed as early as day 7 and in equal amounts during gestation. |
| Domain | The N-terminal part, including the WAC domain and the C motif, mediates the tyrosine-protein kinase activity By similarity. The bromo domain mediates the specific interaction with acetylated histones By similarity. |
| Sequence similarities | Belongs to the WAL family. BAZ1B subfamily. Contains 1 bromo domain. Contains 1 DDT domain. Contains 1 PHD-type zinc finger. Contains 1 WAC domain. |
