High impact information on pAbp

  • Genetic models of junctional plasticity and genetic manipulations using the translation initiation factors eIF4E and poly(A)-binding protein showed an increased occurrence of subsynaptic translation aggregates [1].
  • Here, we demonstrate that ataxin-2 and its Drosophila homolog, ATX2, assemble with polyribosomes and poly(A)-binding protein (PABP), a key regulator of mRNA translation [2].
  • The assembly of ATX2 with polyribosomes is mediated independently by two distinct evolutionarily conserved regions of ATX2: an N-terminal Lsm/Lsm-associated domain (LsmAD), found in proteins that function in nuclear RNA processing and mRNA decay, and a PAM2 motif, found in proteins that interact physically with PABP [2].
  • The PABP transcript accumulates in oocytes, is maternally inherited by the embryo and present at every other developmental stage tested [3].
  • Two classes of cDNAs encoding the Drosophila melanogaster (poly(A)-binding protein (PABP), which differ in length due to different positions of their respective 3' ends, were isolated by screening an embryonic cDNA library [3].

Anatomical context of pAbp

  • We further show that the PAM2 motif mediates a physical interaction of ATX2 with PABP in addition to promoting ATX2 assembly with polyribosomes [2].
  • KLP10A and KLP59C: the dynamic duo of microtubule depolymerization [4].

Analytical, diagnostic and therapeutic context of pAbp

  • A FLAG-tagged poly(A)-binding protein (PABP) is expressed in a specific tissue and mRNA from that tissue is thus tagged by the recombinant PABP and separated from mRNA in other tissues by co-immunoprecipitation with a FLAG-tag specific antibody [5].
