sphingomyelin phosphodiesterase 3 isoform X1 [Homo sapiens]
Protein Classification
sphingomyelin phosphodiesterase( domain architecture ID 10173353)
sphingomyelin phosphodiesterase (sphingomyelinase or SMase) catalyzes the hydrolysis of membrane sphingomyelin to phosphorylcholine and ceramide. Eukaryotic SMases have been classified according to their pH optima and are known as acid SMase, alkaline SMase, and neutral SMase (nSMase). Eukaryotic proteins in this family are nSMases, and are activated by a variety of stress-inducing agents such as cytokines or UV radiation. Ceramides and other metabolic derivatives, including sphingosine, are lipid "second messenger" molecules that participate in the regulation of stress-induced cellular responses, including cell death, adhesion, differentiation, and proliferation. Bacterial neutral SMases, which also belong to this family, are secreted proteins that act as membrane-damaging virulence factors. They promote colonization of the host tissue.

dermokine; Dermokine, also known as epidermis-specific secreted protein SK30/SK89, is a skin-specific glycoprotein that may play a regulatory role in the crosstalk between barrier dysfunction and inflammation, and therefore play a role in inflammatory diseases such as psoriasis. Dermokine is one of the most highly expressed proteins in differentiating keratinocytes, found mainly in the spinous and granular layers of the epidermis, but also in the epithelia of the small intestine, macrophages of the lung, and endothelial cells of the lung. Mouse dermokine has been reported to be encoded by 22 exons, and its expression leads to alpha, beta, and gamma transcripts.
