Previous GeneCards Identifiers for GJB5 Gene
This gene encodes a member of the beta-type (group I) connexin family. The encoded protein is a gap junction protein involved in intercellular communication related to epidermal differentiation and environmental sensing. This gene has been linked to non-small cell lung cancer. [provided by RefSeq, Nov 2012]
GeneCards Summary for GJB5 Gene
GJB5 (Gap Junction Protein Beta 5) is a Protein Coding gene. Diseases associated with GJB5 include Palmoplantar Keratoderma And Congenital Alopecia 1 and Bart-Pumphrey Syndrome. Among its related pathways are Gap junction trafficking and Vesicle-mediated transport. An important paralog of this gene is GJB4.
UniProtKB/Swiss-Prot Summary for GJB5 Gene
One gap junction consists of a cluster of closely packed pairs of transmembrane channels, the connexons, through which materials of low MW diffuse from one cell to a neighboring cell.
Gap channels (gap junctions) are specialized cell-cell contacts that provide direct intracellular communication. They allow passive diffusion of molecules up to 1 kDa, including nutrients, metabolites (glucose), ions (K+, Ca2+) and second messengers (IP3, cAMP).
