CC -!- FUNCTION: Acts as a synaptic organizer in specific subsets of neurons
CC in the brain (PubMed:29691328, PubMed:21410790). Essential for long-
CC term maintenance but not establishment of excitatory synapses
CC (PubMed:29691328 PubMed:30287486). {ECO:0000269|PubMed:21410790,
CC ECO:0000269|PubMed:29691328, ECO:0000269|PubMed:30287486}.
CC -!- SUBUNIT: Homohexamer; disulfide-linked homotrimers. The trimers are
CC assembled via the globular C1q domains. The trimers associate via N-
CC terminal cysteine residues to form disulfide-linked hexamers (By
CC similarity). May form homooligomers or heterooligomers with CBLN1 and
CC CBLN3 prior to secretion (PubMed:29782851). Once secreted, does not
CC interact with other CBLN family members. Interacts with GRID2, and more
CC weakly with GRID1. Interacts with NRXN1 and NRXN2 long and short
CC isoforms produced by alternative promoter usage (PubMed:21410790,
CC PubMed:22220752, PubMed:29782851). Weakly interacts with NRXN3 short
CC isoform and not at all with NRXN3 long isoform (PubMed:22220752,
CC PubMed:29782851). {ECO:0000250|UniProtKB:Q9R171,
CC ECO:0000269|PubMed:17030622, ECO:0000269|PubMed:21410790,
CC ECO:0000269|PubMed:22220752, ECO:0000269|PubMed:29782851}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:17030622,
CC ECO:0000269|PubMed:17331201, ECO:0000269|PubMed:29782851}.
CC -!- TISSUE SPECIFICITY: Expressed in various brain regions with higher
CC levels in the olfactory bulb, cerebral cortex, certain thalamic and
CC hypothalamic nuclei, superior and inferior colliculi and some brainstem
CC nuclei. Highly expressed in the dorsal medial habenula.
CC {ECO:0000269|PubMed:16930405, ECO:0000269|PubMed:29691328,
CC ECO:0000269|PubMed:30287486}.
CC -!- DEVELOPMENTAL STAGE: In the developing brain, expressed as early as 10-
CC 13 dpc. Expression level peaks at 18 dpc and gradually decreases
CC afterwards. {ECO:0000269|PubMed:16930405}.
CC -!- DISRUPTION PHENOTYPE: Mice show impaired synaptic transmission within 3
CC weeks in interpeduncular target neurons whereas significant decrease in
CC both the synapse density and size seen only after 3 months
CC (PubMed:30287486). Display impaired passive avoidance learning, spatial
CC learning and short-term memory (PubMed:30287486). Double CBLN1 and
CC CBLN2 knockout mice exhibit gait abnormalities, impairments in balance
CC and coordination and develop seizures (PubMed:29691328). Synapse
CC density in the hippocampus is normal in 1-2 months old mice, but
CC severely decreased in 6 month old mice (PubMed:29691328). Triple CBLN1,
CC CBLN2 and CBLN4 knockout mice exhibit impairments in sensory processing
CC and sensorimotor gating, in addition to severe motor deficits, seizures
CC and reduced synapse density in the hippocampus of aging mice
CC (PubMed:29691328). {ECO:0000269|PubMed:29691328,
CC ECO:0000269|PubMed:30287486}.
