Function

Atypical tyrosine-protein kinase that plays a central role in chromatin remodeling and acts as a transcription regulator (PubMed:19092802). Involved in DNA damage response by phosphorylating 'Tyr-142' of histone H2AX (H2AXY142ph) (PubMed:19092802, PubMed:19234442). H2AXY142ph plays a central role in DNA repair and acts as a mark that distinguishes between apoptotic and repair responses to genotoxic stress (PubMed:19092802, PubMed:19234442). Regulatory subunit of the ATP-dependent WICH-1 and WICH-5 ISWI chromatin remodeling complexes, which form ordered nucleosome arrays on chromatin and facilitate access to DNA during DNA-templated processes such as DNA replication, transcription, and repair (PubMed:11980720, PubMed:28801535). Both complexes regulate the spacing of nucleosomes along the chromatin and have the ability to slide mononucleosomes to the center of a DNA template (PubMed:28801535). The WICH-1 ISWI chromatin remodeling complex has a lower ATP hydrolysis rate than the WICH-5 ISWI chromatin remodeling complex (PubMed:28801535). The WICH-5 ISWI chromatin-remodeling complex regulates the transcription of various genes, has a role in RNA polymerase I transcription (By similarity). Within the B-WICH complex has a role in RNA polymerase III transcription (PubMed:16603771). Mediates the recruitment of the WICH-5 ISWI chromatin remodeling complex to replication foci during DNA replication (PubMed:15543136).

Activity summary

WSTF also known as Williams Syndrome Transcription Factor or BAZ1B is a versatile protein with an estimated mass around 175 kDa. It is a component of the nucleosome remodeling factor (NURF) and the Williams-Beuren syndrome chromosome region 17 (WBSCR17) complex. WSTF has widespread expression in various tissues including the brain and heart which highlights its involvement in diverse cellular processes. Functionally it facilitates chromatin remodeling by altering the structure of nucleosomes which is vital for DNA accessibility in transcription DNA repair and replication.

Biological function summary

Since WSTF participates in chromatin structure modulation it plays a considerable role in transcriptional regulation. It is a part of the NURF complex which makes it essential for DNA accessibility and gene expression. The complex interacts with other proteins to allow chromatin to accommodate active transcription by repositioning nucleosomes. WSTF also has a kinase domain that phosphorylates histone H2A. This phosphorylation integrates signals that coordinate transcription and DNA damage repair mechanisms highlighting its multifunctional nature in maintaining genomic stability.

Pathways

WSTF has pivotal roles in the chromatin remodeling and DNA repair pathways. The chromatin remodeling pathway involves WSTF's interaction with the transcription factor complex influencing gene accessibility and expression. WSTF in the DNA repair pathway ensures proper genomic integrity through its association with proteins like BRCA1 highlighting its participation in the cellular response to DNA damage. By engaging with these pathways WSTF contributes to the cell's ability to regulate the genome and respond to damage efficiently.

Associated diseases and disorders

WSTF is significantly connected to Williams-Beuren syndrome and certain cancers. Williams-Beuren syndrome a developmental disorder arises from the deletion of the region on chromosome 7 involving the WSTF gene affecting brain and heart function. In certain cancers aberrant expression or mutations within the WSTF gene are associated with uncontrolled chromatin remodeling contributing to tumorigenesis. Through these disorders WSTF shows its interaction with proteins like SMARCA1 in chromatin remodeling anomalies emphasizing its importance in disease progression and cellular dysfunction.

    Release of WSTF was induced by KRASG12V in colon cells(A) We constructed the H-RasG12V expression vectors to preferentially activate the Ras pathways. The levels of P-ERK1/2, P-AKT and RalA-GTP were detected with specific antibodies to examine the activities of corresponding pathways. (B) Media containing WSTF and P-WSTF was detected using ELISA. Levels of intracellular P-WSTF, total WSTF protein and mRNA were detected as controls. (C) Different small interfering RNAs were transfected into HIPECKRASM cells for 48 h. Two specific siRNAs for each gene were implicated in experiments. The secreted WSTF was detected by ELISA assay. (D) The media of HIPECKRASM cells, which was cultured with U0126 (10 μM) or Wortmannin (10 μM) for 20 h, were tested by ELISA. Non-treated HIPECKRASM cells were used as control.
