we report an unexpected finding that CLIP170 negatively regulates TLR4 signaling by the targeted ubiquitination and degradation of TIRAP. Furthermore, we observed that CLIP170 expression is modulated by LPS to maintain the cellular homeostasis.
-
ASK1- induced phosphorylation of EB1 not only increases its plus end-tracking ability, but also promotes its recruitment of CLIP170 and p150glued to astral microtubules.
-
single-molecule fluorescence microscopy showed that the microtubule plus-end-associated protein CLIP-170 binds tightly to formins to accelerate actin filament elongation.
-
We find that LRRK1-mediated phosphorylation of CLIP-170 causes the accumulation of p150(Glued) (also known as DCTN1) a subunit of dynactin, at microtubule plus ends, thereby facilitating the migration of EGFR-containing endosomes.
-
herpesvirus particles are absolutely dependent on CLIP-170-mediated capture to initiate transport in primary human cells.
-
We show that AMPH-1/BIN1 binds to nesprin and actin, as well as to the microtubule-binding protein CLIP170 in both species. We propose that BIN1 has a direct and evolutionarily conserved role in nuclear positioning, altered in myopathies.
-
Restin inhibits epithelial-mesenchymal transition and tumor metastasis by controlling the expression of the tumor metastasis suppressor mir-200a/b via association with p73.
-
CLIP-170 tethers kinetochores to microtubule ends against the dynein-mediated poleward force to slide kinetochores along microtubules
-
A defect in the CLIP1 gene (CLIP-170) can cause autosomal recessive intellectual disability.
-
Data suggest that CLIP-170 acts as a novel recruiter and spatial regulator of PLK1 at kinetochores during early mitosis, promoting K-fiber stability and chromosome alignment for error-free chromosome segregation.
-
siRNA-mediated knockdown of the cytoplasmic linker protein compromised the assembly and branching of capillary-like blood vessels and neovascularization in vivo. It was critical for the motility abilities of HUVECs through its actions on cell polarity.
-
HDAC6 interacts with cytoplasmic linker protein 170 (CLIP-170) and that these two proteins function together to stimulate the migration of pancreatic cancer cells.
-
CLIP-170 phosphorylation by Plk1 regulates proper chromosome alignment
-
Depletion of CLIP-170 significantly impaired vascular endothelial tube formation and sprouting in vitro and inhibited breast tumor growth in mice by decreasing tumor vascularization.
-
We further demonstrate that this binding was prevented when the C-terminal tyrosine of EB1 was absent in the peptidic probes.
-
results suggest that EB1 and ClipCG12 act cooperatively to regulate microtubule dynamics (CLIP-170)
-
End-binding proteins interact with the CAP-Gly domains of CLIP-170 and p150(glued).
-
These results demonstrate that CLIP-170 mediates paclitaxel sensitivity in breast cancer via a microtubule-dependent mechanism.
-
Herein, the authors have identified polo-like kinase 1 (Plk1) and casein kinase 2 (CK2) as two kinases of CLIP-170 and mapped S195 and S1318 as their respective phosphorylation sites.
