Ube4b Gene Summary [Rat]
Enables ATPase binding activity. Predicted to be involved in several processes, including ERAD pathway; granzyme-mediated apoptotic signaling pathway; and protein polyubiquitination. Predicted to act upstream of or within several processes, including proteasome-mediated ubiquitin-dependent protein catabolic process; protein ubiquitination; and ventricular trabecula myocardium morphogenesis. Predicted to be part of ubiquitin ligase complex. Predicted to be active in cytoplasm and nucleus. Orthologous to human UBE4B (ubiquitination factor E4B).

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 Ube4b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
