Talin-1 is a protein that in humans is encoded by the TLN1 gene.[1][2]

This gene encodes a cytoskeletal protein which is concentrated in areas of cell-substratum and cell-cell contacts. This protein plays a significant role in the assembly of actin filaments and in spreading and migration of various cell types, including fibroblasts and osteoclasts. It codistributes with integrins in the cell surface membrane in order to assist in the attachment of adherent cells to extracellular matrices and of lymphocytes to other cells. The N-terminus of this protein contains elements for localization to cell-extracellular matrix junctions. The C-terminus contains binding sites for proteins such as beta-1-integrin, actin, and vinculin.[3]


TLN1 has been shown to interact with PTK2,[4][5] Paxillin[6][7][8] and CD61.[9][10]
