Summary
Enables chromatin binding activity. Predicted to be involved in mitotic spindle assembly and sister chromatid cohesion. Located in chromatin. Is expressed in several structures, including alimentary system; brain; genitourinary system; integumental system; and respiratory system. Human ortholog(s) of this gene implicated in autosomal dominant intellectual developmental disorder 47. Orthologous to human STAG1 (STAG1 cohesin complex component). [provided by Alliance of Genome Resources, Nov 2024]

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.
