About: Unconventional protein secretion

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Unconventional protein secretion (known as ER/Golgi-independent protein secretion or nonclassical protein export ) represents a manner in which the proteins are delivered to the surface of plasma membrane or extracellular matrix independent of the endoplasmic reticulum or Golgi apparatus. This includes cytokines and mitogens with crucial function in complex processes such as inflammatory response or tumor-induced angiogenesis. Most of these proteins are involved in processes in higher eukaryotes, however an unconventional export mechanism was found in lower eukaryotes too. Even proteins folded in their correct conformation can pass plasma membrane this way, unlike proteins transported via ER/Golgi pathway. Two types of unconventional protein secretion are these: signal-peptid-containing pr

  • Unconventional protein secretion (known as ER/Golgi-independent protein secretion or nonclassical protein export ) represents a manner in which the proteins are delivered to the surface of plasma membrane or extracellular matrix independent of the endoplasmic reticulum or Golgi apparatus. This includes cytokines and mitogens with crucial function in complex processes such as inflammatory response or tumor-induced angiogenesis. Most of these proteins are involved in processes in higher eukaryotes, however an unconventional export mechanism was found in lower eukaryotes too. Even proteins folded in their correct conformation can pass plasma membrane this way, unlike proteins transported via ER/Golgi pathway. Two types of unconventional protein secretion are these: signal-peptid-containing proteins and cytoplasmatic and nuclear proteins that are missing an ER-signal peptide (1). (en)
