High impact information on Plxna1

 

Biological context of Plxna1

 

Anatomical context of Plxna1

 

Associations of Plxna1 with chemical compounds

  • Moreover, putative extracellular segments of these two proteins had three repeats of a cysteine-rich domain which is a common motif for plexin proteins [6].
  • Furthermore, we show that plexin-A1 associates with the triggering receptor expressed on myeloid cells-2 (Trem-2), linking semaphorin-signalling to the immuno-receptor tyrosine-based activation motif (ITAM)-bearing adaptor protein, DAP12 [8].
  • Interestingly, integrin-based focal adhesive structures are disassembled within minutes upon plexin activation; this is followed by actin depolymerization and, eventually, by cellular collapse [11].
 

Physical interactions of Plxna1

 

Regulatory relationships of Plxna1

  • Here, we show that plexin-A3 is the most ubiquitously expressed plexin family member within regions of the developing mammalian nervous system known to contain semaphorin-responsive neurons [12].
 

Other interactions of Plxna1

  • Identification and characterization of a novel mouse plexin, plexin-A4 [13].
  • It has been proposed that four members of the plexin A subfamily (plexin-As; plexin-A1, -A2, -A3, and -A4) and two neuropilins (neuropilin-1 and neuropilin-2) form complexes and serve as receptors for class 3 secreted semaphorins (Semas), potent neural chemorepellents [14].
  • Thus, we named these two proteins mouse plexin 2 and mouse plexin 3 [6].
  • A physical and functional association between Met and Plexin B1, the prototype of class B Plexin subfamily, has been previously demonstrated [15].
  • We found the semaphorin receptor plexin-A1 was expressed in DCs, but not in other immune cells, and was strongly induced by CIITA [2].
 

Analytical, diagnostic and therapeutic context of Plxna1

  • Northern blot analysis indicated that mouse plexin 1 was predominantly expressed in the brain [16].
  • MATERIALS AND METHODS: ATDC5 cells and primary chondrocytes were either treated with NOV recombinant protein or transfected with a NOV-specific siRNA to determine, using quantitative RT-PCR, the effect of NOV on the expression of several molecules involved in chondrocyte differentiation [17].
  • Hybridoma antibodies which reacted against the nonoccluded form (NOV) of AcNPV in an ELISA test expressed different specificities for the occluded form of the virus (OV), a mutant strain of AcNPV, and CfNPV [18].
  • The polypeptide specificity of 19 of 28 hybridoma antibodies which reacted with OV and NOV of AcNPV was assigned using Western blot analysis [18].
