Summary: Enables chromatin binding activity. Involved in kidney development; lymphocyte proliferation; and negative regulation of gene expression, epigenetic. Acts upstream of or within several processes, including cellular response to leukemia inhibitory factor; chromosomal DNA methylation maintenance following DNA replication; and negative regulation of intrinsic apoptotic signaling pathway. Located in nucleus and pericentric heterochromatin. Is expressed in several structures, including gut; hippocampus; neural retina; reproductive system; and thymus. Human ortholog(s) of this gene implicated in immunodeficiency-centromeric instability-facial anomalies syndrome 4. Orthologous to human HELLS (helicase, lymphoid specific).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
