Study of Vitellogenin Motif
نویسندگان
چکیده
Vitellogenin (VTG) is known to be a female-specific protein and a precursor form of egg yolk. Threevitellogenin,Vtg I,Vtg II and Vtg III have been identified in chicken.Vitellinogen precursors supply the major egg yolk proteins which are a source of nutrients during early development of egg-laying (oviparous) vertebrates and invertebrates. A complete structural analysis and 3-D modelling of Vitellogenin protein of Chicken (Target), has been already done. The 1852 amino acid sequence of the Vitellogenin protein (Gallus gallus) was retrieved from NCBI database. OOPS model of Multiple EM for Motif Elicitation (MEME) online software package was used to carry out this analysis. Total fifteen amino acid sequences were taken for motif analysis.According to our results, Vitellogenin sequences, contains three motifs. We analyze that all fifteen sequences includes all threemotifs but their start points are different. Motif investigationsuggeststhat all selected VTG sequences from different resources have common conserved patterns.

The cDNA of Apis mellifera vitellogenin was cloned and sequenced. It is 5440 bp long and contains an ORF of 1770 amino acids (including a putative signal peptide of 16 residues). The deduced amino acid sequence shows significant similarity with other hymenopteran vitellogenins (58% with Pimpla nipponica and 54% with Athalia rosae). The alignment with 19 insect vitellogenins shows a high number ...
