ST8SIA4  
    


    
      Official symbol:  ST8SIA4
      Full name:  ST8 alpha-N-acetyl-neuraminide alpha-2,8-sialyltransferase 4
      Location:  5q21.1
      Also known as:  SIAT8D, PST1, PST
      Entrez ID:  7903
      Ensembl ID:  ENSG00000113532
      Summary:  The protein encoded by this gene catalyzes the polycondensation of alpha-2,8-linked sialic acid required for the synthesis of polysialic acid, a modulator of the adhesive properties of neural cell adhesion molecule (NCAM1). The encoded protein, which is a member of glycosyltransferase family 29, is a type II membrane protein that may be present in the Golgi apparatus. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
