dc.description.abstract | Members of the cellular retinoic acid (CRABP) and retinol binding (CRBP) proteins family are involved in the metabolic pathways of retinoic acid (RA) and retinal respectively. The objective of this study is to determine whether such proteins are present in crustaceans. We report here the cloning and isolation of a novel complementary DNA (cDNA) that showed characteristics of the CRABP/CRBP from the ovary and eyestalk of the shrimp. The cDNA is 0.9 Kb in size and the deduced shrimp protein is encoded for a protein of 14 kDa. Although it shows high amino acids sequence similarity to both the vertebrate and invertebrate CRABP, some conserved amino acids identified in other CRABPs were not found in MeCRABP. MeCRABP is expressed in the ovary, eyestalk, testis, epidermis and early larvae. The presence of MeCRABP in early larval stages suggests that the protein may be involved in the early larval development. Recombinant MeCRABP was produced and used to generate a polyclonal antibody. In theimmunohistochemical detection study, anti-rCRABP antibody recognized the presence of CRABP in several cell types of the eyestalk as well as the smaller oocytes of the ovary. Although MeCRABP messenger RNA transcripts can be detected in the ovary throughout the ovarian maturation period, CRABP was detected only in the primary oocytes of the ovary. The results suggest that CRABP transcripts in the mature ovary are not translated and may be supplied to the oocyte as maternal messages. The binding property of the recombinant MeCRABP was also tested by a fluorometeric method. The result indicates that rMeCRABP binds to both RA and retinal with similar affinity. This study represents the first cloning andcharacterization of a cDNA that belongs to a member of retinoid/fatty acid binding protein family in crustaceans. | |
