“…Members of the actin gene family are involved in various cellular processes, including muscle contraction, cell motility, cell division and cytokinesis, vesicle and organelle movement, cell signaling, and the establishment and maintenance of cell junctions, and cell shape [ 31 ]. To date, actin genes have been isolated from several molluscs, including Aplysia californica [ 32 , 33 ], Crassostrea gigas [ 34 ], Placopecten magellanicus [ 30 ], and Patella vulgata [ 35 ]. It is suggest that the actin gene family of the abalone H. iris include at least eight genes; three of these, H. iris A 1, H. iris A 2, and H. iris A 3, are shown to be differentially expressed [ 36 ].…”
