Summary: The protein encoded by this gene belongs to a family of secreted neuronal glycoproteins. The transcript is broadly expressed in the embryonic and adult brain with higher levels in some regions including the olfactory bulb, thalamus, and cerebral cortex. The protein can bind to presynaptic neurexins and induce synaptogenesis in cultured neurons. Null mutant mice are viable, fertile and do not display obvious neuroanatomical defects. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2014]

Cerebellin-2 regulates a serotonergic dorsal raphe circuit that controls compulsive behaviors.
Title: Cerebellin-2 regulates a serotonergic dorsal raphe circuit that controls compulsive behaviors.
Cbln2 and Cbln4 are expressed in distinct MHb neurons that contribute to different behaviors.
Title: Cbln2 and Cbln4 are expressed in distinct medial habenula-interpeduncular projections and contribute to different behavioral outputs.
Findings demonstrate that hippocampal synapse assembly and maintenance require a tripartite molecular complex in which the ligand Cbln2 binds with presynaptic neurexin 1beta (+S4) and postsynaptic GluD1.
Title: Postsynaptic δ1 glutamate receptor assembles and maintains hippocampal synapses via Cbln2 and neurexin.
Results show that Cbln1, Cbln2, and Cbln4 are abundantly expressed in nearly all brain regions, but exhibit strikingly different expression patterns and developmental dynamics. Using newly generated knockin reporter mice for Cbln2 and Cbln4, we find that Cbln2 and Cbln4 are not universally expressed in all neurons, but only in specific subsets of neurons.
Title: Cerebellins are differentially expressed in selective subsets of neurons throughout the brain.
that neurons expressing Cblns 1, 2, and 4 tend to occupy different laminar positions within the dorsal spinal cord
Title: Parcellation of cerebellins 1, 2, and 4 among different subpopulations of dorsal horn neurons in mouse spinal cord.
GluRdelta1 stimulated inhibitory synapse formation in the presence of Cbln1 or Cbln2
Title: Glutamate receptor δ1 induces preferentially inhibitory presynaptic differentiation of cortical neurons by interacting with neurexins through cerebellin precursor protein subtypes.
These results suggest that Cbln1 and Cbln2 play a role in synapse formation of cortical neurons by interacting with NRXNs containing S4.
Title: Differential interactions of cerebellin precursor protein (Cbln) subtypes and neurexin variants for synapse formation of cortical neurons.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
