Spi1 Gene Summary [Mouse]
Enables several functions, including DNA-binding transcription factor activity, RNA polymerase II-specific; NFAT protein binding activity; and histone deacetylase binding activity. Involved in several processes, including lymphocyte differentiation; regulation of macromolecule biosynthetic process; and regulation of myeloid leukocyte mediated immunity. Acts upstream of or within several processes, including apoptotic process involved in blood vessel morphogenesis; hemopoiesis; and regulation of DNA-templated transcription. Located in chromatin and nucleus. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system; and respiratory system. Used to study acute myeloid leukemia. Human ortholog(s) of this gene implicated in agammaglobulinemia 10. Orthologous to human SPI1 (Spi-1 proto-oncogene).

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 Spi1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
