Galanin-Like Peptide (porcine) Trifluoroacetate, H-Ala-Pro-Val-His-Arg-Gly-Arg-Gly-Gly-Trp-Thr-Leu-Asn-Ser-Ala-Gly-Tyr-Leu-Leu-Gly-Pro-Val-Leu-His-Pro-Pro-Ser-Arg-Ala-Glu-Gly-Gly-Gly-Lys-Gly-Lys-Thr-Ala-Leu-Gly-Ile-Leu-Asp-Leu-Trp-Lys-Ala-Ile-Asp-Gly-Leu-Pro-Tyr-Pro-Gln-Ser-Gln-Leu-Ala-Ser-OH, 245114-96-9, C281H443N81O78, Mr 6204.11, 0.5mg. GALP (porcine). 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.
