Small integral membrane protein (SMIM) 20 is a protein that in humans is encoded by the SMIM20 gene. [5] SMIM20 acts as a prohormone to the peptide hormone phoenixin which was discovered for the first time in 2013 in rodent sensory ganglia. [6]

In the study of the evolution of nervous systems, SMIM20 together with NUCB2 have been found to have deep homology across all lineages that preceded creatures with central nervous systems, bilaterians, cnidarians, ctenophores, and sponges as well as in choanoflagellates. [7] [8]

Glypican 2 (GPC2), also known cerebroglycan, is a protein which in humans is encoded by the GPC2 gene. The GPC2 gene is at locus 7q22.1 and encodes for a 579 amino acid protein. The C-terminus of GPC2 has the GPI attachment site, at G554, and the N-terminus encodes a signal peptide, from M1 to S24. Multiple GPC2 mRNA transcripts have been identified. GPC2-201 is the isoform overexpressed in pediatric cancers. Tumor-associated exon 3 of GPC2 shows the lowest expression in normal tissues compared with other exons.
