High impact information on Anxa3

  • Mouse PAP III and two additional truncated forms, PAPs V and VI, which would be produced by use of poly(A) sites in adjacent introns, were also isolated from a mouse brain cDNA library [1].
  • However, annexin III, vimentin, and tropomyosin were down-regulated [2].
  • In contrast, annexin III was removed under these conditions and needed a relatively high Ca2+ concentration to remain phagosome bound [3].
  • The Anx3 locus mapped to the middle of mouse chromosome 5 between Areg and Fgf5 [4].
  • Mouse annexin III cDNA was characterized from I.M.A.G.E. Consortium (LLNL) expressed sequence tag clones by molecular sequencing, chromosomal mapping and systematic analysis. cDNA sequences extended the known 5' and 3' untranslated regions and confirmed the location of intron 7 with respect to the human gene [4].

Biological context of Anxa3

  • In addition, gene knockdown via adenovirus-mediated small interference RNA expression in isolated sciatic nerves successfully suppressed PAP-III expression and its macrophage chemoattractant activity [5].
  • Furthermore, overexpression or knockdown of the PAP-III gene in crushed sciatic nerves in rats resulted in acceleration or retardation of macrophage recruitment and subsequent nerve regeneration, respectively [5].

Anatomical context of Anxa3

  • Of the annexins tested, we found annexin III to be naturally occurring in the oocyte, while only trace amounts of annexins II and V could be demonstrated [6].
  • Collectively, our results demonstrate that PAP-III is a novel macrophage chemoattractant that is involved in peripheral nerve regeneration and further provide new insights into Schwann cell-macrophage interactions and therapeutic interventions [5].
