|Application ||WB, ICC, E|
|Other Accession||P23435, 116114|
|Reactivity||Human, Mouse, Rat|

|Application Notes||Precerebellin antibody can be used for the detection of precerebellin by Western blot at 2 - 4 µg/mL. Antibody can also be used for immunocytochemistry starting at 10 µg/mL.|
|Other Names||Precerebellin Antibody: Cerebellin-1, Precerebellin, CER, cerebellin 1 precursor|
|Reconstitution & Storage||Precerebellin antibody can be stored at 4℃ for three months and -20℃, stable for up to one year. As with all antibodies care should be taken to avoid repeated freeze thaw cycles. Antibodies should not be exposed to prolonged high temperatures.|
|Precautions||Precerebellin Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Required for synapse integrity and synaptic plasticity. During cerebellar synapse formation, essential for the formation and maintenance of parallel fiber and Purkinje cell synapses. When parallel fibers make contact with Purkinje spines, CBLN1 interaction with GRID2 triggers the recruitment of NRXN1 and secretory vesicles to the sites of contact. NRXN1-CBLN1-GRID2 signaling induces presynaptic morphological changes, which may further accumulate pre- and postsynaptic components to promote bidirectional maturation of parallel fiber - Purkinje cell functionnally active synapses by a positive feedback mechanism. Required for CBLN3 export from the endoplasmic reticulum and secretion (By similarity).|
|Cellular Location||Secreted. Cell junction, synapse, postsynaptic cell membrane|
|Tissue Location||In the Purkinje cells postsynaptic structures. In the cerebellum, cerebellin is much less abundant than [des- Ser1]-cerebellin|

Precerebellin Antibody: Precerebellin is the precursor of the brain-specific hexadecapeptide cerebellin, a protein with substantial similarity to the globular region of the B chain of complement component C1q. Cerebellin exerts neuromodulatory functions by directly stimulating norepinephrine release via the adenylate cyclase/pka- dependent signaling pathway; and indirectly enhances adrenocortical secretion in vivo, through a paracrine mechanism involving medullary catecholamine release. The active form of precerebellin is highly enriched in postsynaptic structures of cerebellar Purkinje cells in cartwheel neurons of the dorsal cochlear nucleus. Because precerebellin belongs to the C1q/tumor necrosis factor superfamily of secreted proteins and has similarity to adiponectin and CTRP3, it has been suggested that precerebellin posseses functions other than those already stated.
