Rabbit Anti-Human Precerebellin recognizes an epitope near the C-terminus of Human, Mouse and Rat Precerebellin. This polyclonal antibody was purified using affinity chromatography.

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.¹ Cerebellin exerts neuromodulatory functions by directly stimulating norepinephrine release via the adenylate cyclase/pka- dependent signaling pathway;² and indirectly enhances adrenocortical secretion in vivo, through a paracrine mechanism involving medullary catecholamine release.³ The active form of precerebellin is highly enriched in postsynaptic structures of cerebellar Purkinje cells in cartwheel neurons of the dorsal cochlear nucleus.⁴ 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.
