Fxr1 Gene Summary [Mouse]
Enables mRNA 3'-UTR AU-rich region binding activity; molecular condensate scaffold activity; and ribonucleoprotein complex binding activity. Involved in several processes, including dentate gyrus development; modulation of chemical synaptic transmission; and regulation of gene expression. Located in several cellular components, including costamere; dendritic spine; and ribosome. Is active in several cellular components, including glutamatergic synapse; intracellular membraneless organelle; and postsynapse. Is expressed in several structures, including central nervous system; gut; heart; musculature; and sensory organ. Human ortholog(s) of this gene implicated in congenital myopathy 9A and congenital myopathy 9B. Orthologous to human FXR1 (FMR1 autosomal homolog 1).

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 Fxr1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
