Gjc2 Gene Summary [Mouse]
Enables gap junction channel activity. Acts upstream of or within cell-cell signaling and response to toxic substance. Located in gap junction and myelin sheath. Is expressed in brain; ovary; and spinal cord. Used to study hypomyelinating leukodystrophy 2. Human ortholog(s) of this gene implicated in hereditary lymphedema IC; hereditary spastic paraplegia 44; hypomyelinating leukodystrophy 2; and lymphedema. Orthologous to human GJC2 (gap junction protein gamma 2). [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 Gjc2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
