• The vertebrate head is a complex tapestry of morphological features woven together during embryonic development from a varied array of specialized cell types. (frontiersin.org)
  • We have studied Platynereis orthologs of the most important vertebrate neural bHLH genes, i.e. achaete-scute, neurogenin, atonal, olig , and NeuroD genes, the latter two being genes absent of the Drosophila genome. (biomedcentral.com)
  • These transcription factors have been studied in many metazoans, especially in vertebrates but also in early branching metazoan clades such as the cnidarians and sponges. (biomedcentral.com)
  • The NOTCH1 cell signaling mechanism is conserved in most multicellular organisms including all metazoans (and thus vertebrates). (atlasgeneticsoncology.org)
  • Presenilin is the catalytic component of the γ-secretase complex that is responsible for the cleavage of the transmembrane protein, amyloid precursor protein (APP) (reviewed in D e S trooper 2003 ). (genetics.org)
  • These four transmembrane proteins constitute the γ-secretase core complex, yet little is known about its regulation and activity. (genetics.org)
  • 272,500 Da) consists of a large extracellular unit which associates in a calcium-dependent, non-covalent interaction with a second unit consisting of the following: a small extracellular region, a single transmembrane spanning region, and a small intracellular region. (atlasgeneticsoncology.org)
