Pja2 Gene Summary [Rat]
Predicted to enable protein kinase A catalytic subunit binding activity; protein kinase A regulatory subunit binding activity; and ubiquitin protein ligase activity. Involved in long-term memory and regulation of protein kinase A signaling. Is active in glutamatergic synapse and postsynaptic density. Orthologous to human PJA2 (praja ring finger ubiquitin ligase 2). [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 rat Pja2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
