Gene: Gjb1 (gap junction protein, beta 1) Mus musculus
Symbol: Gjb1
Name: gap junction protein, beta 1
Description: Exhibits identical protein binding activity. Predicted to be involved in cell-cell signaling and purine ribonucleotide transport. Localizes to cytoplasm; gap junction; and plasma membrane. Is expressed in several structures, including forelimb; gut; inner ear; liver; and metanephros. Used to study Charcot-Marie-Tooth disease X-linked dominant 1. Human ortholog(s) of this gene implicated in Charcot-Marie-Tooth disease X-linked dominant 1. Orthologous to human GJB1 (gap junction protein beta 1).
Type: protein-coding
RefSeq Status: REVIEWED
