The invention discloses an establishing method of a bacterial artificial chromosome recombinant duck plague virus rescue system platform and application of the platform. A bacterial artificial chromosome recombinant duck plague virus is obtained by inserting a recombinant duck plague virus transfer vector pUC18/EGFP-TKAB-BAC11 in a TK domain, wherein the recombinant duck plague virus transfer vector contains a TK gene left-right homologous arm, a reporter gene EGFP and a bacterial artificial chromosome core function component. By means of the platform, the in-vitro biologics characteristics of a UL55 gene-deleted strain established through an inside-bacterium two-step RED recombination method and a back mutation strain and parent strain of the UL55 gene-deleted strain are quite close; the functions are not related to positioning of a UL26.5 gene in a cell. The method is beneficial to development of pathogenic mechanism and gene function research of DPV CHv and is beneficial to the duck plague virus prevention and the research and application of recombinant duck plague virus vaccines of other poultry infectious diseases based on the platform; in addition, due to the fact that the recombinant virus carries a TK deletion mark and an EGFP gene, a mark vaccine can be developed to clinically distinguish a wild virus and a recombinant vaccine virus.

The invention discloses a microtubule-associated protein and coding genes and application thereof. The microtubule-associated protein is protein of (a) or (b): (a) protein formed by an amino acid sequence as shown by a sequence one in a sequence table; and (b) protein derived by the sequence one, related to the inhibition of the microtubule de-polymerization activity of MCAK protein and formed ina way the amino acid sequence of the sequence one is substituted and/or deleted and/or added by one to ten amino acid residues.
