SLK-mediated actin cytoskeletal reorganization may facilitate force transmission between the contractile units and the extracellular matrix.
Title: Ste20-like Kinase-mediated Control of Actin Polymerization Is a New Mechanism for Thin Filament-associated Regulation of Airway Smooth Muscle Contraction.
The inhibition of SLK by RNA interference significantly suppressed the invasion ability of glioma, and on protein level, knock- down of SLK leaded to an up-regulation of E-cadherin and a down-regulation of Vimentin in glioma cells.
Title: Ste20-like kinase is upregulated in glioma and induces glioma invasion.
SLK interacts with Tpr and alpha-actinin-4 in cells, and these protein-protein interactions may control the subcellular localization and the biological activity of SLK.
Title: Identification of Tpr and α-actinin-4 as two novel SLK-interacting proteins.
SLK activated ERMs, together with Galphai, are critical for the correct localization of LGN-NuMA force generator complexes and hence for proper spindle orientation.
Title: SLK-dependent activation of ERMs controls LGN-NuMA localization and spindle orientation.
The fact that SLK (LOSK) phosphorylates only a minor isoform 1A of p150(Glued) suggests that transport and microtubule-organizing functions of dynactin are distinctly divided between the two isoforms
Title: Ste20-like protein kinase SLK (LOSK) regulates microtubule organization by targeting dynactin to the centrosome.
It was shown that lymphocyte-oriented and STE20 kinase were sufficient to restrict ezrin function to the apical domain. Both kinases were enriched in microvilli and locally activated there.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
