What is the function of this protein?
Involved in transcriptional regulation and chromatin remodeling.  Facilitates DNA replication in multiple cellular environments and is required for efficient replication of a subset of genomic loci.  Binds to DNA tandem repeat sequences in both telomeres and euchromatin and in vitro binds DNA quadruplex structures.  May help stabilizing G-rich regions into regular chromatin structures by remodeling G4 DNA and incorporating H3. 3-containing nucleosomes.  Catalytic component of the chromatin remodeling complex ATRX:DAXX which has ATP-dependent DNA translocase activity and catalyzes the replication-independent deposition of histone H3. 3 in pericentric DNA repeats outside S-phase and telomeres, and the in vitro remodeling of H3. 3-containing nucleosomes.  Its heterochromatin targeting is proposed to involve a combinatorial readout of histone H3 modifications (specifically methylation states of H3K9 and H3K4) and association with CBX5.  Involved in maintaining telomere structural integrity in embryonic stem cells which probably implies recruitment of CBX5 to telomeres.  May be involved in transcriptional regulation of telomeric repeat-containing RNA (TERRA).  Acts as negative regulator of chromatin incorporation of transcriptionally repressive histone MACROH2A1, particularily at telomeres.  Participates in the allele-specific gene expression at the imprinted IGF2/H19 gene locus.  On the maternal allele, required for the chromatin occupancy of SMC1 and CTCTF within the H19 imprinting control region (ICR) and involved in esatblishment of histone tails modifications in the ICR.  May be involved in brain development and facial morphogenesis.  Binds to zinc-finger coding genes with atypical chromatin signatures and regulates its H3K9me3 levels.  Forms a complex with ZNF274, TRIM28 and SETDB1 to facilitate the deposition and maintenance of H3K9me3 at the 3' exons of zinc-finger genes (By similarity).
What are the official names of this protein?
Transcriptional regulator ATRX, ATP-dependent helicase ATRX, X-linked helicase II, X-linked nuclear protein, XNP.
What is the protein family that this protein belongs to?
Belongs to the SNF2/RAD54 helicase family.
What are the subcellular locations of this protein?
Nucleus. Chromosome, telomere. Nucleus, PML body. Note=Associated with pericentromeric heterochromatin during interphase and mitosis, probably by interacting with CBX5/HP1 alpha. Colocalizes with histone H3.3, DAXX, HIRA and ASF1A at PML-nuclear bodies. Colocalizes with cohesin (SMC1 and SMC3) and MECP2 at the maternal H19 ICR (By similarity).
