Gene type: protein coding
RefSeq status: VALIDATED
Organism: Homo sapiens
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Also known as: BSX1
Summary: Enables sequence-specific double-stranded DNA binding activity. Predicted to be involved in cell differentiation; regulation of transcription by RNA polymerase II; and stem cell population maintenance. Predicted to act upstream of or within several processes, including eating behavior; mammary gland involution; and positive regulation of transcription by RNA polymerase II. Predicted to be located in chromatin. Predicted to be part of transcription regulator complex. [provided by Alliance of Genome Resources, May 2025]

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.
