Selank is a synthetic heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) built on tuftsin, an endogenous tetrapeptide (Thr-Lys-Pro-Arg) derived from the Fc region of immunoglobulin G. The C-terminal Pro-Gly-Pro extension was added to the tuftsin core to slow enzymatic breakdown, which is why Selank is studied as a more stable tuftsin analog. It is used in laboratory settings to study regulatory peptides, neuropeptide signaling and peptide-driven changes in gene expression.

Selank belongs to a family of synthetic peptides designed by extending a short natural regulatory peptide with a Pro-Gly-Pro tail to improve stability. Its parent sequence, tuftsin, has a long history in immunology research, and Selank has been examined for whether it keeps some of that immunomodulatory character. In mouse spleen, researchers measured the expression of inflammation-related genes after Selank administration and reported shifts in a defined subset of them.1
A second line of work looks at the nervous system. Using rat frontal cortex tissue, investigators profiled genes involved in GABAergic neurotransmission and reported that Selank administration changed the expression of several of them, which has made the peptide a reference tool in studies of GABA-related signaling at the transcript level.2
