LSP1 and supervillin interact with a similar subset of myosin IIA regulators. a Western blots of macrophage lysates progressively extracted by increased concentration of TritonX-100 (1–5%), or in RIPA buffer. Note that LSP1, and also myosin IIA, are mostly extracted in the 2% and RIPA fractions. b Western blot of immunoprecipitation of endogenous LSP1 or myosin IIA from macrophage lysates, with control IgG and input. Blots were probed with indicated antibodies. Note cross-coprecipitation of LSP1 and myosin IIA, accompanied by coprecipitation of myosin regulators MLCK and calmodulin. Molecular weight in kDa is indicated. c Western blots of anti-GFP immunoprecipitation of lysates from macrophages expressing LSP1 full length or LSP1 domains fused to GFP (For inputs, see Supplementary Fig. 7A). Blots were probed with indicated antibodies. Note coprecipitation of myosin IIA with full length LSP1, and also with the C-terminal and the villin headpiece-like domains (V1V2) of LSP1. Interestingly only the full length and the C-terminal constructs, but not V1V2, are also able to bind MLCK, pMLC and calmodulin. An LSP1-positive band in the lane of the C-terminal construct probably reflects the fact that the anti-LSP1 antibody recognizes an epitope in the C-terminal half of LSP1. d Immunoprecipitation of myosin IIA from macrophage lysates, with addition of Mg2+/ATP and/or latrunculin A (10 µM), as indicated. Upper panel : colloidal Coomassie stained SDS PAGE gel, lower panels : corresponding western blots developed with indicated antibodies. Molecular weight is indicated in kDa. e Quantification of coprecipitated amounts of actin and LSP1, normalized to precipitations performed without addition of Mg2+/ATP and/or latrunculin A. f Western blots of anti-GFP immunoprecipitations from lysates of macrophages expressing LSP1-GFP or supervillin construct SV1-830-GFP developed with indicated primary antibodies. Molecular weight in kDa is indicated. Note that LSP1 and SV1-830 coprecipitate comparable amounts of myosin IIA, MLCK and calmodulin, but that supervillin-coprecipitated myosin is more activated, as indicated by pMLC signal

Actomyosin relaxation enables survival upon E-cadherin loss. a Merged brightfield and GFP images of MMECs isolated from Wcre;mTmG and Wcre;Cdh1F/F;mTmG female mice in the absence or presence of 10 µM Y-27632. Asterisks indicate areas of zoom, red dotted lines display outgrowth of E-cadherin-deficient MMECs. Zooms display altered cell adhesion in the absence or presence of Y-27632 of GFP-positive E-cadherin-deficient cells derived from Wcre;Cdh1F/F;mTmG female mice. Scale bar, 50 µm. b Western blot analysis of Wcre;mTmG and Wcre;Cdh1F/F;mTmG MMECs stained for E-cadherin and tubulin (loading control). c Western blot analysis of subclones derived from the Wcre;mTmG and Wcre;Cdh1F/F;mTmG MMECs stained for E-cadherin and tubulin (loading control). d Brightfield images of MMECs 3 h post seeding in the absence or presence of 10 µM Y-27632 or 10 µM blebbistatin.
