cortistatin-29

Cortistatin-29 is a neuropeptide that is structurally similar to somatostatin-28. It is produced by cleavage of preprocortistatin to procortistatin, which is cleaved at dibasic amino acids to form cortistatin-29 and cortistatin-14 as well as other partial cleavage products. Cortistatin mRNA is expressed in the human brain and in interneurons of the rat hippocampus and cerebral cortex. Cortistatin-29 binds to somatostatin (SST) receptors with IC50 values of 2.8, 7.1, 0.2, 3, and 13.7 nM for SST1-5, respectively. Cortistatin-29 is found at similar levels as cortistatin-14 in mouse AtT20 cells but is secreted at a lower level. Cortistatin-29 corresponds to residues 85-112 of the rat peptide sequence.

Cortistatin 29, a neuropeptide, alleviates neuropathic pain and exhibits anti-fibrotic effects. It binds with high affinity to all somatostatin (SS) receptor subtypes, displaying IC 50 values of 2.8 nM for SSTR1, 7.1 nM for SSTR2, 0.2 nM for SSTR3, 3.0 nM for SSTR4, and 13.7 nM for SSTR5, respectively [1] [2] [3] [4].

Cortistatin-29 (1-13) is a neuropeptide and cleavage product of cortistatin-29 , which is a cleavage product of procortistatin. Cortistatin-29 (1-13) corresponds to the first 13 amino acids of cortistatin-29.
