Abstract
Abstract Disclosed are (1) a polypeptide (I) including the following amino acid sequence (II) in a molecule thereof: TyrAlaGluHisLysSerHisArgGlyGluTyrSerValCys AspSerGluSerLeuTrpValThrAspLysSerSerAlaIle AspIleArgGlyHisGlnValThrValLeuGlyGluIleLys ThrGlyAsnSerProValLysGlnTyrPheTyrGluThrArg CysLysGluAlaArgProValLysAsnGlyCysArgGlyIle AspAspLysHisTrpAsnSerGlnCysLysThrSerGlnThr TyrValArgAlaLeuThrSerGluAsnAsnLysLeuValGly TrpArgTrpIleArgIleAspThrSerCysValCysAlaLeu SerArgLysIleGlyArg (II) (2) a DNA sequence coding for the polypeptide described in (1), (3) a vector including the DNA described in (2), (4) a transformant transformed by the vector described in (3), and (5) a process for producing the polypeptide (I) which comprises cultivating the transformant described in (4) in a culture medium to produce and accumulate the polypeptide described in (1) in a culture. The polypeptide is useful as a reagent for studies relating to the differentiation, growth and survival of animal cells, and may also be useful as a drug.
