Mib2 Gene Summary [Rat]
Predicted to enable ubiquitin protein ligase activity. Involved in regulation of postsynaptic neurotransmitter receptor internalization and regulation protein catabolic process at postsynapse. Is active in glutamatergic synapse and postsynapse. Orthologous to human MIB2 (MIB E3 ubiquitin protein 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 Mib2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
