The protein family consists of serine proteases involved in regulated intramembrane proteolysis (RIP) of various substrates, playing a crucial role in cellular signaling and regulation. These proteases cleave after hydrophobic or small residues, with a preference for Arg or Lys at the P4 position. They are responsible for the proteolytic activation of sterol regulatory element-binding proteins (SREBPs), cyclic AMP-dependent transcription factors (ATF6 and ATF6B), and other factors like BDNF, GNPTAB, and FAM20C. This activation process is essential for lipid homeostasis, lysosome biogenesis, osteoblast differentiation, and ER stress response. Additionally, they regulate M6P-dependent trafficking of lysosomal enzymes and are involved in collagen trafficking through the activation of CREB3L2/BBF2H7. In plants, they participate in stress response signaling and cell wall remodeling by processing factors like BZIP17 and pectinesterases. Overall, the family plays a key role in various cellular processes, including lipid metabolism, stress response, and developmental pathways.

Subtilases are a family of serine proteases. They appear to have independently and convergently evolved an Asp/Ser/His catalytic triad, like that found in the trypsin serine proteases (see Pfam:PF00089). Structure is an alpha/beta fold containing a 7-stranded parallel beta sheet, order 2314567.
