Pmp22 Gene Summary [Rat]
Predicted to enable cytoskeletal motor activity and protein serine/threonine kinase inhibitor activity. Involved in several processes, including myelination; negative regulation of cell population proliferation; and negative regulation of neuron projection development. Located in bicellular tight junction and compact myelin. Biomarker of sciatic neuropathy. Human ortholog(s) of this gene implicated in Charcot-Marie-Tooth disease (multiple); Guillain-Barre syndrome; and hereditary neuropathy with liability to pressure palsies. Orthologous to human PMP22 (peripheral myelin protein 22). [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 rat Pmp22 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
