The Other SCN (Suprachiasmatic Nucleus) and the connection to SCN- (thiocyanate)
These two entities share the same abbreviation (SCN), yet reside in vastly different terrains: one biochemical (thiocyanate), the other neuroanatomical (suprachiasmatic nucleus). Let’s explore whether they intersect, metaphorically or materially.… Read more.

Corticotropin-like intermediate [lobe] peptide (CLIP)
Corticotropin-like intermediate [lobe] peptide (CLIP), also known as adrenocorticotropic hormone fragment 18-39 (ACTH(18-39)), is a naturally occurring, endogenous neuropeptide with a docosapeptide structure and the amino acid sequence Arg-Pro-Val-Lys-Val-Tyr-Pro-Asn-Gly-Ala-Glu-Asp-Glu-Ser-Ala-Glu-Ala-Phe-Pro-Leu-Glu-Phe. CLIP is generated as a proteolyic cleavage product of adrenocorticotropic hormone (ACTH), Gianoulakis C, Seidah NG, Routhier… Read more.

Pro-opiomelanocortin (POMC)
Pro-opiomelanocortin (POMC) is a precursor polypeptide with 241 amino acid residues. POMC is synthesized in corticotrophs of the anterior pituitary from the 267-amino-acid-long polypeptide precursor pre-pro-opiomelanocortin (pre-POMC), by the removal of a 26-amino-acid-long signal peptide sequence during translation. “pro-opiomelanocortin preproprotein [Homo sapiens] – Protein – NCBI”. www.ncbi.nlm.nih.gov.… Read more.
