Gap Junction beta-1 Protein

A GAP JUNCTION beta subunit containing four transmembrane domains expressed in myelinating SCHWANN CELLS and is localized to peripheral MYELIN (e.g., noncompact myelin in the paranode and Schmitt-Lanterman incisures). Mutations in the human gene GJB1 are associated with X-linked CHARCOT-MARIE-TOOTH DISEASE type 1 (CMT1X).
