TNS1
Function
May act as a protein phosphatase and/or a lipid phosphatase (Probable). Involved in fibrillar adhesion formation (PubMed:21768292, PubMed:28005397). Essential for myofibroblast differentiation and myofibroblast-mediated extracellular matrix deposition (PubMed:28005397). Enhances RHOA activation in the presence of DLC1 (PubMed:26427649). Plays a role in cell polarization and migration (PubMed:19826001). May be involved in cartilage development and in linking signal transduction pathways to the cytoskeleton (PubMed:21768292).
Post-translational modifications
Extensively phosphorylated on serine and threonine residues in a p38 MAPK-dependent manner which reduces interaction with DLC1 and increases interaction with tyrosine-phosphorylated proteins including BCAR1/p130cas and PTK2/FAK. The majority of the phosphorylated Ser/Thr residues are immediately adjacent to a proline residue. Also phosphorylated on tyrosine residues.
Rapidly cleaved by calpain II.
Sequence Similarities
Belongs to the PTEN phosphatase protein family.
Tissue Specificity
In the lung, detected in the alveolar septa (at protein level) (PubMed:28005397). Ubiquitous (PubMed:11023826).
Cellular localization
- Cell surface
- Cell junction
- Focal adhesion
- Cytoplasm
- Cytoskeleton
- Localizes to both focal adhesions and fibrillar adhesions (PubMed:20069572). Localized at the cell periphery preferentially to fibrillar adhesions rather than to focal adhesions. Translocates from the cell edge to the cell center in an ITGB1BP1-dependent manner (PubMed:21768292).
