WebJan 1, 2014 · Moreover, ADP-ribosylated actin acts like a capping protein to block polymerization at the barbed (plus) ends of F-actin. This causes enhanced depolymerization of the actin cytoskeleton. The depolymerization of cortical actin, which is located beneath the cell membrane, results in formation of long protrusions, which are microtubule based. Webisolated a Drosophila homologue of the yeast cyclase-associated protein, CAP. Here we show that CAP preferentially accumulates in the oocyte, where it inhibits actin polymerisation. CAP also has a role in oocyte polarity, as cap mutants fail to establish the proper, asymmetric distribution of mRNA determinants within the oocyte.
