    Structural basis of kindlin-mediated integrin recognition and activation.
    Proc Natl Acad Sci U S A 2017 Jul 24. Epub 2017 Jul 24.
    Department of Biology, Southern University of Science and Technology, Shenzhen 518055, China;
    Kindlins and talins are integrin-binding proteins that are critically involved in integrin activation, an essential process for many fundamental cellular activities including cell-matrix adhesion, migration, and proliferation. As FERM-domain-containing proteins, talins and kindlins, respectively, bind different regions of β-integrin cytoplasmic tails. However, compared with the extensively studied talin, little is known about how kindlins specifically interact with integrins and synergistically enhance their activation by talins. Read More

    Focal adhesions in the skin: lessons learned from skin fragility disorders.
    Eur J Dermatol 2017 Jun;27(S1):8-11
    Department of Dermatology, Medical Center - University of Freiburg, Faculty of Medicine, University of Freiburg, Germany.
    Focal adhesions are large multiprotein cell-matrix adhesion complexes, which regulate multiple cellular functions, such as adhesion and migration. Their biological significance in skin is underscored by two genetic disorders, the Kindler syndrome and the interstitial lung disease, nephrotic syndrome and epidermolysis bullosa, in which mutations affect focal adhesion proteins, kindlin-1 and the integrin α3 subunit, respectively. Here we provide an overview of what we learned from the study of the molecular mechanisms of these diseases. Read More

    Edinburgh Cancer Research UK Centre, Institute of Genetics & Molecular Medicine, University of Edinburgh, Crewe Road South, Edinburgh EH4 2XR, UK. Electronic address:
    Kindlin-1 is a FERM domain containing adaptor protein that is found predominantly at cell-extracellular matrix adhesions where it binds to β-integrin subunits and is required for integrin activation. Loss of function mutations in the FERMT1 gene which encodes Kindlin-1 leads to the development of Kindler Syndrome (KS) an autosomal recessive skin disorder characterized by skin blistering, photosensitivity, and predisposition to aggressive squamous cell carcinoma (SCC). Here we show that loss of Kindlin-1 sensitizes both SCC cells and keratinocytes to oxidative stress: Kindlin-1 deficient cells have higher levels of reactive oxygen species, decreased viability and increased DNA damage after treatment with either hydrogen peroxide (H2O2) or irradiation with UVA.

    Kindlin1 regulates microtubule function to ensure normal mitosis.
    J Mol Cell Biol 2016 Aug 18;8(4):338-48. Epub 2016 Mar 18.
    Edinburgh Cancer Research Centre, Institute of Genetics & Molecular Medicine, University of Edinburgh, Crewe Road South, Edinburgh EH4 2XR, UK
    Loss of Kindlin 1 (Kin1) results in the skin blistering disorder Kindler Syndrome (KS), whose symptoms also include skin atrophy and reduced keratinocyte proliferation. Kin1 binds to integrins to modulate their activation and more recently it has been shown to regulate mitotic spindles and cell survival in a Plk1-dependent manner. Here we report that short-term Kin1 deletion in mouse skin results in impaired mitosis, which is associated with reduced acetylated tubulin (ac-tub) levels and cell proliferation. Read More

    The kindlin family: functions, signaling properties and implications for human disease.
    J Cell Sci 2016 Jan;129(1):17-27
    Max Planck Institute of Biochemistry, Martinsried 82152, Germany
    The kindlin (or fermitin) family of proteins comprises three members (kindlin-1,-2 and -3) of evolutionarily conserved focal adhesion (FA) proteins, whose best-known task is to increase integrin affinity for a ligand (also referred as integrin activation) through binding of β-integrin tails. The consequence of kindlin-mediated integrin activation and integrin-ligand binding is cell adhesion, spreading and migration, assembly of the extracellular matrix (ECM), cell survival, proliferation and differentiation. Another hallmark of kindlins is their involvement in disease. Read More

    Recently Identified Forms of Epidermolysis Bullosa.
    Ann Dermatol 2015 Dec 7;27(6):658-66. Epub 2015 Dec 7.
    St John's Institute of Dermatology, King's College London (Guy's Campus), London, UK.
    Epidermolysis bullosa (EB) comprises a collection of clinically diverse inherited blistering diseases that affect the skin and, in some subtypes, mucous membranes and other organs. Currently classified into four main subtypes (EB simplex, junctional EB, dystrophic EB, and Kindler syndrome, mainly based on the level of skin cleavage), the spectrum of EB extends to more than 30 clinical subtypes with pathogenic mutations in at least 18 distinct genes. This review focuses on three recent additions to variants of EB: all are autosomal recessive, and result from mutations in either DST-e (coding for epidermal dystonin, also known as the 230 kDa bullous pemphigoid antigen, BP230), EXPH5 (coding for exophilin-5, also known as Slac2-b), or ITGA3 (coding for the integrin alpha-3 subunit).

    Kindler syndrome in mice and men.
    Cancer Biol Ther 2014 Sep 11;15(9):1113-6. Epub 2014 Jun 11.
    Department of Dermatology; University of Pennsylvania; Philadelphia, PA USA.
    Kindler syndrome (KS) in humans is a severe skin blistering disease associated with inflammation and increased risk of epidermal squamous cell carcinoma (SCC). This disease is known to be caused by loss-of-function mutations in Kindlin-1, a focal adhesion β-integrin binding protein. Thus far, it has been unclear what specific signaling events occur in KS keratinocytes to promote tumorigenesis, especially since loss of β-integrins and focal adhesion complexes has been previously shown to prevent or delay tumor formation.

    The genetics of skin fragility.
    Annu Rev Genomics Hum Genet 2014 29;15:245-68. Epub 2014 May 29.
    Department of Dermatology, Medical Center-University of Freiburg, Freiburg 79104, Germany; email:
    Genetic skin fragility manifests with diminished resistance of the skin and mucous membranes to external mechanical forces and with skin blistering, erosions, and painful wounds as clinical features. Skin fragility disorders, collectively called epidermolysis bullosa, are caused by mutations in 18 distinct genes that encode proteins involved in epidermal integrity and dermal-epidermal adhesion. The genetic spectrum, along with environmental and genetic modifiers, creates a large number of clinical phenotypes, spanning from minor localized lesions to severe generalized blistering, secondary skin cancer, or early demise resulting from extensive loss of the epidermis.

    Kindlin-1 controls Wnt and TGF-β availability to regulate cutaneous stem cell proliferation.
    Nat Med 2014 Apr 30;20(4):350-9. Epub 2014 Mar 30.
    Department of Molecular Medicine, Max Planck Institute of Biochemistry, Martinsried, Germany.
    Kindlin-1 is an integrin tail binding protein that controls integrin activation. Mutations in the FERMT-1 gene, which encodes for Kindlin-1, lead to Kindler syndrome in man, which is characterized by skin blistering, premature skin aging and skin cancer of unknown etiology. Here we show that loss of Kindlin-1 in mouse keratinocytes recapitulates Kindler syndrome and also produces enlarged and hyperactive stem cell compartments, which lead to hyperthickened epidermis, ectopic hair follicle development and increased skin tumor susceptibility.

    New intragenic and promoter region deletion mutations in FERMT1 underscore genetic homogeneity in Kindler syndrome.
    Clin Exp Dermatol 2014 Apr;39(3):361-7
    Department of Dermatology, Tel Aviv Sourasky Medical Center, Tel Aviv, Israel; Department of Human Molecular Genetics and Biochemistry, Sackler Faculty of Medicine, Tel Aviv University, Ramat Aviv, Israel.
    Background: Kindler syndrome (KS) is a rare autosomal recessive skin disorder, which was recently reclassified as a subtype of epidermolysis bullosa. Despite the fact that loss-of-function mutations in the FERMT1 gene, encoding kindlin-1, have been shown to cause the syndrome in numerous patients, a small number of typical cases of KS in which FERMT1 mutations could not be identified has raised the possibility that the disorder may be genetically heterogeneous.

    Aim: To assess two highly consanguineous families with clinical characteristics of KS. Read More
