Are Vitellin and Vitellogenin Coded by One Gene in the Marine Shrimp Penaeus semisulcatus?
in Journal of Molecular EndocrinologyABSTRACT
A cDNA clone encoding a female-specific ovarian protein (presumably vitellin, Vt) has been isolated from a cDNA library prepared from poly (A)+ RNA extracted from vitellogenic ovaries of the shrimp Penaeus semisulcatus. The cDNA library was constructed and screened using a major cDNA band which was observed following analysis of total cDNA products by gel electrophoresis. This band, as well as the cDNA insert purified from the library, was estimated to have 1.1 kb. Both hybridized to mRNA prepared from ovaries or hepatopancreas (HEP) of vitellogenic females and showed a faint signal with ovaries from non-vitellogenic females, but did not hybridize to HEP from non-vitellogenic females or to HEP from males or testes. The size of the transcripts from the ovary and HEP was estimated to be 1.1 kb, similar to that of the cDNA insert, suggesting that a full length cDNA had been synthesized. Furthermore, the identical sizes of the transcripts from ovary and HEP and the ability of the ovarian cDNA to detect a transcript in HEP mRNA suggest that Vt from the ovary and vitellogenin (Vg) from HEP are the gene products of one gene. Alternatively, the homology between Vt and Vg is very high.
Journal of Molecular Endocrinology is committed to supporting researchers in demonstrating the impact of their articles published in the journal.
The two types of article metrics we measure are (i) more traditional full-text views and pdf downloads, and (ii) Altmetric data, which shows the wider impact of articles in a range of non-traditional sources, such as social media.
