Study of Vitellogenin Motif

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 themajor 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 ofVitellogenin protein of Chicken (Target), has been already done. The 1852 amino acid sequence of theVitellogenin protein (Gallus gallus) was retrieved from NCBI database. OOPS model of Multiple EM forMotif Elicitation (MEME) online software package was used to carry out this analysis. Total fifteen aminoacid sequences were taken for motif analysis.According to our results, Vitellogenin sequences, containsthree motifs. We analyze that all fifteen sequences includes all threemotifs but their start points aredifferent. Motif investigationsuggeststhat all selected VTG sequences from different resources havecommon conserved patterns.
