• Sequence Length: 242

• Applicable Applications for CASP14 recombinant protein: ELISA (EIA), Western Blot (WB), Antigen Protein (AP), Protein Array
• Species: Human
• Tag: His
• Subunit: Heterodimer of a large and a small subunit, both processed from the precursor; the mature active form is a p17/p10 dimer and the intermediate form a p20/p8 dimer.
• Entry 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).
• Preparation and Storage: Store at -20 degree C. Avoid repeated freezing and thawing.

NCBI Description

This gene encodes a member of the cysteine-aspartic acid protease (caspase) family. Sequential activation of caspases plays a central role in the execution-phase of cell apoptosis. Caspases exist as inactive proenzymes which undergo proteolytic processing at conserved aspartic residues to produce two subunits, large and small, that dimerize to form the active enzyme. This caspase has been shown to be processed and activated by caspase 8 and caspase 10 in vitro, and by anti-Fas agonist antibody or TNF-related apoptosis inducing ligand in vivo. The expression and processing of this caspase may be involved in keratinocyte terminal differentiation, which is important for the formation of the skin barrier. [provided by RefSeq, Jul 2008]

Uniprot Description

CASP14: Believed to be a non-apoptotic caspase which is involved in epidermal differentiation. Seems to play a role in keratinocyte differentiation and cornification. Probably regulates maturation of the epidermis by proteolytically processing filaggrin. Complex of unprocessed caspase-14 and processed 19 kDa (p19) and 10 kDa (p10) subunits. In undifferentiated keratinocytes under postconfluency growth conditions (in vitro). Expressed in keratinocytes of adult skin suprabasal layers (from spinous layers to the stratum granulosum and stratum corneum). Expressed in keratinocytes of hair shaft and sebaceous glands. In psoriatic skin only expressed at very low levels. Belongs to the peptidase C14A family.
