Connexins

Gap junction beta-2 protein (GJB2), also known as connexin 26 (Cx26) — is a protein that in humans is encoded by the GJB2 gene.

Gap junction alpha-1 protein (GJA1), also known as connexin 43 (Cx43), is a protein that in humans is encoded by the GJA1 gene on chromosome 6. As a connexin, GJA1 is a component of gap junctions, which allow for gap junction intercellular communication (GJIC) between cells to regulate cell death, proliferation, and differentiation. As a result of its function, GJA1 is implicated in many biological processes, including muscle contraction, embryonic development, inflammation, and spermatogenesis, as well as diseases, including oculodentodigital dysplasia (ODDD), heart malformations, and cancers

Gap junction beta-4 protein (GJB4), also known as connexin 30.3 (Cx30.3) — is a protein that in humans is encoded by the GJB4 gene.

Gap junction alpha-3 protein is a protein that in humans is encoded by the GJA3 gene.

Gap junction gamma-2 (GJC2), also known as connexin-46.6 (Cx46.6) and connexin-47 (Cx47) and gap junction alpha-12 (GJA12), is a protein that in humans is encoded by the GJC2 gene.

Gap junction beta-3 protein (GJB3), also known as connexin 31 (Cx31) — is a protein that in humans is encoded by the GJB3 gene.

Gap junction alpha-4 protein, also known as Connexin-37 or Cx37, is a protein that in humans is encoded by the GJA4 gene. This protein, like other Connexin proteins, forms connections between cells known as gap junctions. Connexin 37 can be found in many tissues including the ovary, heart, and kidney.

Gap junction gamma-3, also known as connexin-29 (Cx29) or gap junction epsilon-1 (GJE1), is a protein that in humans is encoded by the GJC3 gene.

Gap junction alpha-8 protein is a protein that in humans is encoded by the GJA8 gene. It is also known as connexin 50.

Gap junction gamma-1 protein (GJC1), also known as gap junction alpha-7 protein (GJA7) and connexin 45 (Cx45) — is a protein that in humans is encoded by the GJC1 gene.

Gap junction alpha-10 protein, also known as connexin-62 (Cx62), is a protein that in humans is encoded by the GJA10 gene.

Gap junction alpha-5 protein (GJA5), also known as connexin 40 (Cx40) — is a protein that in humans is encoded by the GJA5 gene.

Gap junction beta-7 protein (GJB7), also known as connexin-25 (Cx25), is a protein that in humans is encoded by the GJB7 gene.

Gap junction delta-4 protein (GJD4), also known as connexin-40.1 (Cx40.1), is a protein that in humans is encoded by the GJD4 gene.
