PCSK6
| View/Edit Human | View/Edit Mouse |
Proprotein convertase subtilisin/kexin type 6 is an enzyme that in humans is encoded by the PCSK6 gene.[4][5] PCSK6 is a protease that cleaves NODAL into an active form to help trigger the development of left/right (LR) asymmetry.[6] It may also be involved in left and right handedness in humans.[7][8][9]
Function
The protein encoded by this gene belongs to the subtilisin-like proprotein convertase family. The members of this family are proprotein convertases that process latent precursor proteins into their biologically active products. This encoded protein is a calcium-dependent serine endoprotease that can cleave precursor protein at their paired basic amino acid processing sites. Some of its substrates are - transforming growth factor beta related proteins, proalbumin, and von Willebrand factor. Alternatively spliced transcript variants encoding different isoforms have been identified.[5]
PCSK6 also cleaves and activates corin, a serine protease that regulates sodium homeostasis and blood pressure.[10]
Clinical significance
This gene is thought to play a role in tumor progression.[5]
PCSK6 deficiency causes salt-sensitive hypertension in mice.[10]
