Ctbp2 Gene Summary [Rat]
Predicted to enable several functions, including nuclear retinoic acid receptor binding activity; transcription coregulator activity; and transcription corepressor binding activity. Predicted to be a structural constituent of presynaptic active zone. Predicted to be involved in regulation of DNA-templated transcription; synaptic vesicle docking; and white fat cell differentiation. Predicted to act upstream of or within cellular response to leukemia inhibitory factor; positive regulation of retinoic acid receptor signaling pathway; and positive regulation of transcription by RNA polymerase II. Predicted to be located in ribbon synapse. Predicted to be part of transcription repressor complex. Predicted to be active in several cellular components, including photoreceptor ribbon synapse; presynaptic active zone cytoplasmic component; and presynaptic cytosol. Orthologous to human CTBP2 (C-terminal binding protein 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 Ctbp2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
