Summary: Predicted to enable gap junction channel activity. Acts upstream of or within regulation of satellite cell activation involved in skeletal muscle regeneration. Located in plasma membrane. Is expressed in several structures, including diaphragm; limb segment; liver; lung; and skeletal musculature. Orthologous to human GJD4 (gap junction protein delta 4).

Data show that myogenesis in Cx39 KO mice is accelerated by increased myogenin expression on ED13.5 and 16.5 and increased Cx43 in developing skeletal muscle, and suggest that Cx43 may compensate for loss of Cx39 during myogenesis and regeneration.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
