Hapln1a is required for connexin43-dependent growth and patterning in the regenerating fin skeleton.

Abstract excerpt

Cell-cell communication, facilitating the exchange of small metabolites, ions and second messengers, takes place via aqueous proteinaceous channels called gap junctions. Connexins (cx) are the subunits of a gap junction channel. Mutations in zebrafish cx43 produces the short fin (sof (b123) ) phenotype and is characterized by short fins due to reduced segment length of the bony fin rays and reduced cell...
