This family includes the proteinase B inhibitor from Saccharomyces cerevisiae and the activation peptides from peptidases of the subtilisin family. The subtilisin propeptides are known to function as molecular chaperones, assisting in the folding of the mature peptidase [1], but have also been shown to act as 'temporary inhibitors' [2].	Domain

This entry represents a subdomain found in the C-terminal cysteine/histidine-rich domain (CRD) of PCSK9 (also known as neural apoptosis-regulated convertase, NARC-1) [1]. PCSK9 has been shown to regulate circulating LDL-R levels by controlling LDL-R degradation. Furthermore, numerous mutations in the PCSK9 gene have been identified and associated with hypercholesterolemia (gain of function) or hypocholesterolemia (loss of function) [2]. The fully folded CRD, shows structural similarity to the resistin homotrimer, a small cytokine associated with obesity and diabetes. The C-terminal domain from PCSK9 consists of three, three-stranded beta-subdomains arranged in a pseudothreefold, and each of the subdomains in the CRD of PCSK9 consists of three structurally conserved disulfide bonds [1].
