Lat Gene Summary [Mouse]
Predicted to enable molecular condensate scaffold activity; protein kinase binding activity; and signaling receptor complex adaptor activity. Acts upstream of or within gene expression; inflammatory response; and lymphocyte homeostasis. Located in cell-cell junction and immunological synapse. Part of COP9 signalosome. Is expressed in liver and thymus primordium. Used to study IgG4-related disease. Human ortholog(s) of this gene implicated in immunodeficiency 52. Orthologous to human LAT (linker for activation of T cells). [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 Lat often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
