Degs1 Gene Summary [Mouse]
Enables retinol isomerase activity and sphingolipid delta-4 desaturase activity. Acts upstream of or within ceramide biosynthetic process and positive regulation of apoptotic process. Predicted to be located in mitochondrion. Is expressed in several structures, including alimentary system; cardiovascular system; genitourinary system; nervous system; and sensory organ. Human ortholog(s) of this gene implicated in hypomyelinating leukodystrophy 18. Orthologous to human DEGS1 (delta 4-desaturase, sphingolipid 1). [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 Degs1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
