Cerebellin
Cerebellin is a neuromodulatory hexadecapeptide that serves as a marker for Purkinje cell maturation. Cerebellin stimulates norepinephrine release via the adenylate cyclase/PKA-dependent signaling pathway. Cerebellin reduces insulin secretion from pancreatic islets under high-glucose conditions. Cerebellin also regulates synaptic structure formation and controls catecholamine secretion in peripheral tissues. Cerebellin can be used in neurological research.

Biological Activity
Cerebellin (1-100 nM; 10-30 min) potently stimulates the production of norepinephrine and cyclic adenosine monophosphate in rat adrenal medullary tissues via an adenylate cyclase/PKA-dependent pathway[1].
Cerebellin (1-100 nM; 90 min) inhibits glucose-stimulated insulin secretion from isolated rat islets[2].
Cerebellin (100 nM-1 μM; 1 hour) inhibits glucose/Exendin-4 (HY-13443)-stimulated insulin secretion in INS-1 cells[2].
Cerebellin (10 nM-1 μM; 5 min) reduces Forskolin (HY-15371)-induced cAMP accumulation in INS-1 cells in a concentration-dependent manner[2].
Cerebellin (100 nM) irreversibly reduces the intracellular free calcium concentration in INS-1 cells[2].

Cerebellin (0.5-1.5 nmol/100 g body weight; subcutaneous injection; single bolus) acts as an insulin inhibitor in healthy female Wistar rats[2].

Peptide Solubility and Storage Guidelines:
1. Calculate the length of the peptide.
2. Calculate the overall charge of the entire peptide according to the following table:
| Contents | Assign value | |
| Acidic amino acid | Asp (D), Glu (E), and the C-terminal -COOH. | -1 |
| Basic amino acid | Arg (R), Lys (K), His (H), and the N-terminal -NH2 | +1 |
| Neutral amino acid | Gly (G), Ala (A), Leu (L), Ile (I), Val (V), Cys (C), Met (M), Thr (T), Ser (S), Phe (F), Tyr (Y), Trp (W), Pro (P), Asn (N), Gln (Q) | 0 |
3. Recommended solution:
| Overall charge of peptide | Details |
| Negative (<0) |
1. Try to dissolve the peptide in water first. 2. If water fails, add NH4OH (<50 μL). 3. If the peptide still does not dissolve, add DMSO (50-100 μL) to solubilize the peptide. |
| Positive (>0) |
1. Try to dissolve the peptide in water first. 2. If water fails, try dissolving the peptide in a 10%-30% acetic acid solution. 3. If the peptide still does not dissolve, try dissolving the peptide in a small amount of DMSO. |
| Zero (=0) |
1. Try to dissolve the peptide in organic solvent (acetonitrile, methanol, etc.) first. 2. For very hydrophobic peptides, try dissolving the peptide in a small amount of DMSO, and then dilute the solution with water to the desired concentration. |
