Caspase-14 Protein Overview: Sequence, Structure, Function and Protein Interaction

Caspase-14 Protein Overview

Caspase-14 reagents

Using database searches for caspase sequences, Van de Craen et al. (1998) identified CASP14 in human genomic sequence data and cloned both human and mouse CASP14 cDNAs. By Northern blot and RT-PCR analyses, Van de Craen et al. (1998) detected Casp14 expression in mouse skin and developing mouse embryos (embryonic day 7, 15, 16, and 17). Expression generally increased during maturation of the mouse embryo but dropped temporarily to an undetectable level around embryonic day 11 to 12. The authors suggested that Casp14 may play a role in ontogenesis and skin physiology. Eckhart et al. (2000) cloned a full-length CASP14 cDNA encoding a 242-amino acid protein with potential AP1 (165160) and KLF4 (602253) interaction sites. They identified 2 CASP14 transcripts, designated CASP14a and CASP14b, that differ in the C terminus due to a shifted open reading frame. Use of an alternative splice acceptor site within intron 5 results in a 74-nucleotide insertion in CASP14b. CASP14b lacks homology with the caspase consensus sequence and does not have a counterpart in mouse. In situ hybridization analysis detected CASP14 within the epidermis, in hair follicles, and in the cells of the sebaceous glands, with highest expression in the keratogenous zone and the inner root sheeth of the hair follicle and in the peripheral cells of the sebaceous glands. Using immunohistochemical analysis, Denecker et al. (2007) confirmed that mouse Casp14 was expressed only in cornifying epithelia, such as the epidermis and Hassall bodies, and in forestomach, which is cornified like epidermis.
