| UniProt functional annotation for P58772 | |||
| UniProt code: P58772. |
| Organism: | Oryctolagus cuniculus (Rabbit). | |
| Taxonomy: | Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Glires; Lagomorpha; Leporidae; Oryctolagus. | |
| Function: | Binds to actin filaments in muscle and non-muscle cells. Plays a central role, in association with the troponin complex, in the calcium dependent regulation of vertebrate striated muscle contraction. Smooth muscle contraction is regulated by interaction with caldesmon. In non-muscle cells is implicated in stabilizing cytoskeleton actin filaments. {ECO:0000250|UniProtKB:P09493}. | |
| Subunit: | Homodimer (PubMed:23832280). Heterodimer of an alpha (TPM1, TPM3 or TPM4) and a beta (TPM2) chain (By similarity). Interacts with HRG (via the HRR domain); the interaction contributes to the antiangiogenic properties of the histidine/proline-rich region (HRR) of HRG (By similarity). Interacts (via N-terminus) with LMOD2 (via N- terminus) and TMOD1 (via N-terminus) (By similarity). {ECO:0000250|UniProtKB:P04268, ECO:0000250|UniProtKB:P04692, ECO:0000250|UniProtKB:P09493, ECO:0000269|PubMed:23832280}. | |
| Subcellular location: | Cytoplasm, cytoskeleton {ECO:0000250|UniProtKB:P04692}. Note=Associates with F-actin stress fibers. {ECO:0000250|UniProtKB:P04692}. | |
| Domain: | The molecule is in a coiled coil structure that is formed by 2 polypeptide chains. The sequence exhibits a prominent seven-residues periodicity. | |
| Ptm: | Phosphorylated at Ser-283 by DAPK1 in response to oxidative stress and this phosphorylation enhances stress fiber formation in endothelial cells. {ECO:0000250}. | |
| Similarity: | Belongs to the tropomyosin family. {ECO:0000305}. | |
