Pde8b Gene Summary [Mouse]
Enables 3',5'-cyclic-AMP phosphodiesterase activity. Acts upstream of or within several processes, including behavioral fear response; learning; and negative regulation of steroid hormone biosynthetic process. Is expressed in several structures, including alimentary system; central nervous system; hindlimb digit; metanephros; and sensory organ. Human ortholog(s) of this gene implicated in primary pigmented nodular adrenocortical disease 3. Orthologous to human PDE8B (phosphodiesterase 8B).

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 Pde8b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
