Cers3 Gene Summary [Mouse]
Enables sphingosine N-acyltransferase activity. Involved in ceramide biosynthetic process and cornification. Acts upstream of or within sphingolipid biosynthetic process. Located in endoplasmic reticulum. Is expressed in epidermis; epidermis granular layer; epidermis spinous layer; face skin; and skin. Human ortholog(s) of this gene implicated in autosomal recessive congenital ichthyosis 9. Orthologous to human CERS3 (ceramide synthase 3). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Cers3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.

- transcription regulator
- sphingosine N-acyltransferase
