This human neuropeptide of the RFamide peptide family with orexigenic activity may be also involved in the control of feeding behavior. The 26RFa gene is exclusively expressed in the ventromedial hypothalamic nucleus and in the lateral hypothalamic area. The primary structures of human, rat, and frog 26RFa exhibit ≈80% identity. Other data suggest also the potential role of the 26RFa peptide in the control of the gonadotropic axis.

Thymosin β10Arg is a thymosin β4-like peptide that contains an additional amino acid, arginine, inserted following lysine-38.

Autocamtide 2, amide is a substrate (100 μM final concentration) for CaMK family assays.Autocamtide-2 Peptide is a highly selective peptide substrate for calcium/calmodulin-dependent protein kinase II (CaMKII), a member of the CAMK Ser/Thr protein kinase family.
