| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Involved in cell adhesion. Contributes to integrin activation. When coexpressed with talin, potentiates activation of ITGA2B. Required for normal keratinocyte proliferation. Required for normal polarization of basal keratinocytes in skin, and for normal cell shape. Required for normal adhesion of keratinocytes to fibronectin and laminin, and for normal keratinocyte migration to wound sites. May mediate TGF-beta 1 signaling in tumor progression. Ref.8 Ref.9 Ref.11 |
| Subunit structure | Interacts with the cytoplasmic domain of integrins ITGB1 and ITGB3. Ref.8 |
| Subcellular location | Cytoplasm › cytoskeleton. Cell junction › focal adhesion. Cell projection › ruffle membrane; Peripheral membrane protein; Cytoplasmic side. Note: Constituent of focal adhesions. Localized at the basal aspect of skin keratinocytes, close to the cell membrane. Colocalizes with filamentous actin. Upon TGFB1 treatment, it localizes to membrane ruffles. Ref.2 Ref.8 Ref.9 Ref.11 |
| Tissue specificity | Expressed in brain, skeletal muscle, kidney, colon, adrenal gland, prostate, and placenta. Weakly or not expressed in heart, thymus, spleen, liver, small intestine, bone marrow, lung and peripheral blood leukocytes. Overexpressed in some colon and lung tumors. In skin, it is localized within the epidermis and particularly in basal keratocytes. Not detected in epidermal melanocytes and dermal fibroblasts. Ref.1 Ref.2 Ref.7 Ref.8 Ref.9 |
| Induction | By TGFB1. Ref.8 |
| Domain | The FERM domain is not correctly detected by PROSITE or Pfam techniques because it contains the insertion of a PH domain. The FERM domain contains the subdomains F1, F2 and F3. It is preceded by a F0 domain with a ubiquitin-like fold. The F0 domain is required for integrin activation and for localization at focal adhesions. Ref.11 |
| Involvement in disease | Kindler syndrome (KINDS) [MIM:173650]: Autosomal recessive skin disorder characterized by skin blistering, photosensitivity, progressive poikiloderma, and extensive skin atrophy. Additional clinical features include gingival erosions, ocular, esophageal, gastrointestinal and urogenital involvement, and an increased risk of mucocutaneous malignancy. |
| Sequence similarities | Belongs to the kindlin family. Contains 1 FERM domain. Contains 1 PH domain. |
| Sequence caution | The sequence BAA91358.1 differs from that shown. Reason: Erroneous initiation. The sequence BAC03826.1 differs from that shown. Reason: Erroneous initiation. |
