Definitions

  • clathrin tripods self-assemble to form a closed polyhedral structure known as a "cage."
  • clathrin's polyhedral assembly forms a coating cavity that increases in the curved portion by swallowing extracellular environment-derived substances.
  • Another object of the present invention is to provide a method for diagnosing and treating a disease associated with an abnormality of human clathrin light chain 11.
  • the invention also relates to a method for screening compounds that mimic, activate, antagonize or inhibit the activity of human clathrin light chain 11 protein, which comprises utilizing the polypeptide of the invention.
  • the invention also relates to compounds obtained by this method.
  • coli Streptomyces
  • bacterial cells such as Salmonella typhimurium
  • fungal cells such as yeast
  • plant cells such as fly S2 or Sf9
  • animal cells such as CH0, COS or Bowes melanoma cells.
  • Transformation of a host cell with a DNA sequence described in the present invention or a recombinant vector containing the DNA sequence can be performed using conventional techniques well known to those skilled in the art.
  • the host is a prokaryote, such as E. coli
  • competent cells capable of absorbing DNA can be harvested after the exponential growth phase and treated with the CaCl 2 method. The steps used are well known in the art. Alternatively, MgCl 2 is used. If necessary, transformation can also be performed by electroporation.
  • the host is a eukaryotic organism, the following DNA transfection methods can be used: calcium phosphate co-precipitation method, or conventional mechanical methods such as microinjection, electroporation, and liposome packaging.
  • the medium used in the culture may be selected from various conventional mediums. Culture is performed under conditions suitable for host cell growth. After the host cells have grown to an appropriate cell density, the selected promoter is induced by a suitable method (such as temperature conversion or chemical induction), and the cells are cultured for a period of time.
  • a suitable method such as temperature conversion or chemical induction
  • Antibodies can also be used to design immunotoxins that target a particular part of the body.
  • Human clathrin light chain Human clathrin light chain
  • the polynucleotide encoding human clathrin light chain 11 can also be used for a variety of therapeutic purposes. Gene therapy technology can be used to treat abnormal cell proliferation, development, or metabolism caused by the non-expression or abnormal / inactive expression of human clathrin light chain 11.
  • Recombinant gene therapy vectors (such as viral vectors) can be designed to express mutated human clathrin light chain 11 to inhibit endogenous human clathrin light chain 11 activity.
  • a mutated human clathrin light chain 11 may be a shortened human clathrin light chain 11 lacking a signaling domain, and although it can bind to a downstream substrate, it lacks signaling activity.
