During experiments on mice, the researchers identified a protein, called neuropsin
, which is made in the amygdala, the brain's "fear centre".
(Opn5) is expressed in predominantly neural tissues .
The protein neuropsin
is regulated by the amygdala, a region deep in the brain that plays a key role in emotional responses.
New British-led research suggests neuropsin
underlies an individual's susceptibility to stress.
KLK8 was originally cloned from a human skin library (9) as a homolog of a gene encoding mouse neuropsin
. The KLK8 peptidase is present in numerous human tissues (10) and is involved in several physiological and pathologic processes (11, 12).
Serine proteinase inhibitor 3 and murinoglobulin | are potent inhibitors of neuropsin
in adult mouse brain.
[According to the official kallikrein gene nomenclature, KLK8 is the gene and hK8 is the protein (8).] Originally, KLK8 was cloned from a human skin cDNA library as a homolog of mouse neuropsin
(61) have shown that KLKS (also known as neuropsin
and TADG-14) is differentially expressed in ovarian cancer.
Two additional kallikrein genes, KLKS (also known as neuropsin
or TADG-14) (18) and the gene that encodes stratum corneum chymotryptic enzyme (19,20) are upregulated in ovarian cancer.

The peropsins are members of the larger Tetraopsin lineage, which includes neuropsins
, Go-opsins, retinal G protein-coupled receptor opsins, and retinochromes (Ramirez et al., 2016).
