Fosl1 Gene Summary [Mouse]
Enables RNA polymerase II transcription regulatory region sequence-specific DNA binding activity and promoter-specific chromatin binding activity. Acts upstream of or within several processes, including placenta blood vessel development; toll-like receptor signaling pathway; and vitellogenesis. Predicted to be located in nucleoplasm and presynaptic membrane. Predicted to be part of RNA polymerase II transcription regulator complex. Predicted to be active in nucleus. Is expressed in several structures, including extraembryonic component; genitourinary system; limb mesenchyme; and lung. Human ortholog(s) of this gene implicated in stomach cancer. Orthologous to human FOSL1 (FOS like 1, AP-1 transcription factor subunit). [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 Fosl1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
