Cerebellin-3 (CBLN3) is a member of the cerebellin protein family, a group of secreted glycoproteins predominantly expressed in the central nervous system, particularly the cerebellum. This family, comprising CBLN1 to CBLN4. is evolutionarily conserved and structurally characterized by a conserved N-terminal cerebellin domain and a C-terminal cysteine-rich domain. CBLN3. like its paralogs, is thought to play roles in synaptic organization and neural circuit formation, though its specific functions remain less defined compared to CBLN1. which is known to interact with presynaptic neurexins and postsynaptic glutamate delta receptors (GluD) to mediate synapse formation.
Recombinant CBLN3 refers to the engineered protein produced in heterologous expression systems (e.g., E. coli, mammalian cells) for experimental studies. Its production enables detailed biochemical and functional analyses, overcoming challenges posed by low endogenous expression levels. Structurally, recombinant CBLN3 retains conserved motifs critical for protein-protein interactions, including six cysteine residues forming disulfide bonds that stabilize its tertiary structure. These features suggest potential involvement in extracellular matrix remodeling or trans-synaptic signaling, though its precise binding partners and signaling pathways are under investigation.
Interest in CBLN3 stems from its potential links to neurodevelopmental and psychiatric disorders. Altered expression of cerebellin family proteins has been implicated in autism spectrum disorders, schizophrenia, and cerebellar ataxia. Recombinant CBLN3 facilitates studies exploring its role in synaptic plasticity, neuronal connectivity, or disease mechanisms. However, functional redundancy within the cerebellin family and the lack of specific antibodies or knockout models have hindered progress. Current research focuses on characterizing its spatiotemporal expression, interactome, and in vivo effects using recombinant tools, aiming to clarify its contribution to neural development and pathology.
