Pig Galanin-Like Peptide Trifluoroacetate
Supplier: BACHEM AMERICAS INC
This member of the galanin family has been isolated from porcine hypothalamus. It is a 60 amino acid peptide that, unlike galanin, has a non-amidated C-terminus. GALP amino acid residues (9-21) are identical to the biologically active N-terminal (1-13) portion of galanin. Receptor binding studies revealed that GALP had a high affinity for the galanin receptor 2 (GALR2; IC₅₀ = 0.24 nM) and a lower affinity for the GALR1 receptor (IC₅₀ = 4.3 nM). GALP is therefore an endogenous ligand that preferentially binds the GALR2 receptor, whereas galanin is relatively non-selective.
