• DNA methyltransferases
  21 November 2003

  Patterns of DNA methylation are laid out during early embryogenesis via the interplay of at least three active DNA methyltransferases, DNMT1, DNMT3A, and DNMT3B, and targeted deletions of these genes in the mouse have demonstrated that the enzymes are essential for normal development.
  DNMT1 associates with the DNA replication fork and functions as a hemi-methylase responsible for maintaining correct methylation patterns on DNA replication. DNMT3s (DNMT3A and DNMT3B) are instead de novo (...)

  enzyme WKP
  Definition : Enzymes are proteins that act as biological catalysts (biocatalysts). Catalysts accelerate chemical reactions.
  The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products.
  Almost all metabolic processes in the cell need enzyme catalysis in order to occur at rates fast enough to sustain life.
  The metabolic pathways depend upon enzymes to catalyze individual steps.

• RNA-binding proteins
  30 November 2003

  Function
  RNA-binding proteins are involved in various aspects of RNA metabolism such as processing, translational control, stabilization, localization and transport.
  Many of these proteins bind several RNA targets and have multiple functions.
  Feautures
  RNA transport
  RNA localization
  RNA metabolism
  RNA splicing
