Targeting of p0071 to the midbody depends on KIF3 is a research paper published in Journal of Cell Science (2009). On theSindex it has a DataRank of 1.7. It has been cited 38 times, with 33 citing works in its 1-hop citation network. Its calibrated FAIR score is 43/100.
P0071 (plakophilin-4) is a member of the p120ctn subfamily of armadillo proteins that are essential for cell contact formation. Additionally, p0071 plays a role in cytokinesis, in which it regulates local activation of RhoA together with Ect2. Because spatiotemporal regulation is required for progression through cytokinesis, we analyzed when and how p0071 is targeted to the midbody to induce RhoA activation. We show that Ect2 precedes p0071 accumulation at the midbody and that targeting is mediated by different motor proteins. p0071 interacted with the kinesin-II family member KIF3b, and knockdown of KIF3b interfered with p0071 midbody recruitment whereas Ect2 or RhoA localization was not affected in these cells. Moreover, knockdown of KIF3b induced a similar phenotype as the p0071 knockdown, with reduced actin and phospho-myosin-light-chain accumulation at the midbody and decreased levels of active RhoA during cytokinesis. The lack of RhoA activation in KIF3b-deficient cells was not rescued by overexpression of wild-type p0071 but was substantially ameliorated by a p0071–MKLP1-motor-domain fusion protein that was targeted to the furrow independently of KIF3. These data indicate that p0071 and Ect2 are transported via distinct motors and identify a novel pathway implicating KIF3 in the regulation of actin organization during cytokinesis.

Base Score Contribution
0.550
From this paper's citation signal
Citation Network Contribution
1.1
From 29 citing papers with measurable signal
Ranked by citation count — the same ordering the engine uses when summing log1p(Cq) over citers.
DataRank blends this paper's own citation count with the influence of the papers that cite it. Here, roughly 32% comes from its base citations and 68% from the citation network (29 citing papers contributed measurable signal).
Citers are pulled from OpenAlex sorted by cited_by_count:descand capped per paper, so when the cap binds we keep the highest-signal references and the score is reproducible across reruns.
