Ssb Gene Summary [Mouse]
Enables RNA binding activity. Predicted to be involved in several processes, including IRES-dependent viral translational initiation; RNA metabolic process; and protein localization to cytoplasmic stress granule. Located in nucleus. Is expressed in several structures, including central nervous system; early conceptus; gonad; sensory organ; and spleen. Orthologous to human SSB (small RNA binding exonuclease protection factor La). [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 Ssb often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
