Arid1b Gene Summary [Mouse]

Predicted to enable DNA binding activity. Predicted to contribute to nucleosome binding activity. Acts upstream of or within dendritic cell dendrite assembly; dendritic spine development; and neuron-neuron synaptic transmission. Located in nucleus. Part of nBAF complex. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; respiratory system; and sensory organ. Used to study Coffin-Siris syndrome 1 and autism spectrum disorder. Human ortholog(s) of this gene implicated in Coffin-Siris syndrome; Coffin-Siris syndrome 1; intellectual disability; lung non-small cell carcinoma; and neuroblastoma. Orthologous to human ARID1B (AT-rich interaction domain 1B). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains

A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Arid1b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
