Protein attributes
| Sequence length | 909 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Involved in skeletal muscle regeneration, specifically at the onset of cell fusion. Also involved in macrophage-derived giant cells (MGC) and osteoclast formation from mononuclear precursors By similarity. |
| Cofactor | Binds 1 zinc ion per subunit. |
| Subunit structure | Interacts with alpha-actinin-2 and with syndecans By similarity. Interacts with SH3PXD2A. Interacts with FST3. Interacts with GNB2L1/RACK1; the interaction is required for PKC-dependent translocation of ADAM12 to the cell membrane. Ref.8 Ref.9 Ref.10 Ref.11 |
| Subcellular location | Isoform 1: Cell membrane; Single-pass type I membrane protein. |
| Tissue specificity | Isoform 1 is expressed in placenta and skeletal, cardiac, and smooth muscle. Isoform 2 seems to be expressed only in placenta or in embryo and fetus. Both forms were expressed in some tumor cells lines. Not detected in brain, lung, liver, kidney or pancreas. |
| Domain | The cysteine-rich domain supports cell adhesion through syndecans and triggers signaling events that lead to beta-1 integrin-dependent cell spreading. In carcinomas cells the binding of this domain to syndecans does not allow the integrin-mediated cell spreading. The conserved cysteine present in the cysteine-switch motif binds the catalytic zinc ion, thus inhibiting the enzyme. The dissociation of the cysteine from the zinc ion upon the activation-peptide release activates the enzyme. |
| Post-translational modification | The precursor is cleaved by a furin endopeptidase By similarity. |
| Sequence similarities | Contains 1 disintegrin domain. Contains 1 EGF-like domain. Contains 1 peptidase M12B domain. |
