Spot pattern of leopard Danio is caused by mutation in the zebrafish connexin41.8 gene. EMBO Rep. 2006;7:893-7 pubmed b>Leopard, a well-known zebrafish mutant that has a spotted skin pattern instead of stripes, is a model for the study of pigment patterning... Watanabe M, Kondo S. Changing clothes easily: connexin41.8 regulates skin pattern variation. Pigment Cell Melanoma Res. 2012;25:326-30 pubmed publisher ..including a narrow stripe with a wide interstripe, a narrow stripe with a narrow interstripe, a labyrinth, and a 'leopard' pattern (or donut-like ring pattern). In this process, connexin41... Watanabe M, Watanabe D, Kondo S. Polyamine sensitivity of gap junctions is required for skin pattern formation in zebrafish. Sci Rep. 2012;2:473 pubmed publisher ..This is the first report to show that polyamine sensitivity has a physiologically relevant function and is related to skin pattern formation in animals. .. Iovine M, Gumpert A, Falk M, Mendelson T. Cx23, a connexin with only four extracellular-loop cysteines, forms functional gap junction channels and hemichannels. FEBS Lett. 2008;582:165-70 pubmed ..Functional assays reveal that the Cx23 gap junctions are capable of sharing neurobiotin, and further, that Cx23 connexins form hemichannels in vitro. ..

J Biol Chem. 2016;291:1053-63 pubmed publisher ..Our results suggest that functional differences in Cx41.8 and Cx39.4 relate to spot or labyrinth mutant phenotypes and also provide evidence that these two connexins interact in vivo and in vitro. ..
