GJB1

Gap junction beta-1 protein (GJB1), also known as connexin 32 (Cx32) — is a is_associated_with::protein that in humans is encoded by the GJB1 is_associated_with::gene.

Function
Connexins are membrane-spanning proteins that assemble to form gap junction channels that facilitate the transfer of ions and small molecules between cells. For a general discussion of connexin proteins, see is_associated_with::GJB2.

In melanocytic cells GJB1 gene expression may be regulated by MITF.
