| Post Translational Modifications | Maturation by proteolytic processing appears to be a two-step process. The precursor is processed by KLK7 to yield the p20/p8 intermediate form which acts on the precursor to yield the p17/p10 mature form. Initially, cleavage between Ile-152 and Lys-153 has been proposed to yield the large and small subunits of the active enzyme. |
| Function | Non-apoptotic caspase involved in epidermal differentiation. Is the predominant caspase in epidermal stratum corneum. Seems to play a role in keratinocyte differentiation and is required for cornification. Regulates maturation of the epidermis by proteolytically processing filaggrin. In vitro has a preference for the substrate WY-X-X-D motif and is active on the synthetic caspase substrate WEHD-ACF. Involved in processing of prosaposin in the epidermis. May be involved in retinal pigment epithelium cell barrier function. Involved in DNA degradation in differentiated keratinocytes probably by cleaving DFFA/ICAD leading to liberation of DFFB/CAD. |
