FUNCTION: Non-apoptotic caspase involved in epidermal differentiation. Is the predominant caspase in epidermal stratum corneum (PubMed:15556625). Seems to play a role in keratinocyte differentiation and is required for cornification. Regulates maturation of the epidermis by proteolytically processing filaggrin (By similarity). In vitro has a preference for the substrate [WY]-X-X-D motif and is active on the synthetic caspase substrate WEHD-ACF (PubMed:16854378, PubMed:19960512). Involved in processing of prosaposin in the epidermis (By similarity). May be involved in retinal pigment epithelium cell barrier function (PubMed:25121097). Involved in DNA degradation in differentiated keratinocytes probably by cleaving DFFA/ICAD leading to liberation of DFFB/CAD (PubMed:24743736). {ECO:0000250|UniProtKB:O89094, ECO:0000269|PubMed:15301553, ECO:0000269|PubMed:15556625, ECO:0000269|PubMed:16854378, ECO:0000269|PubMed:19960512, ECO:0000269|PubMed:22825846, ECO:0000269|PubMed:24743736, ECO:0000305|PubMed:25121097}.
