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. From Wikipedia
Validated in vivo through connexins Cx37 and Cx40 mapping; this mechanism could enhance fMRI interpretation and point to new neurodegenerative therapies
