| Primary Identifier | IPR036064 | Type | Domain |
| Short Name | MYSc_Myo18 |
| description | Many members of myosin class XVIII contain an N-terminal PDZ domain which is commonly found in proteins establishing molecular complexes. Mammals express a second isoform, Myo18B, that lacks the PDZ domain []. They also contain a motor domain which does not exhibit ATPase activity, suggesting that these myosins function as an actin tether protein [, ]. They also have two IQ domains that probably bind light chains or related calmodulins and a C-terminal tail with two sections of coiled-coil domains, which are thought to mediate homodimerization []. Myo18A has been implicated in stromal cell differentiation []and Myo18B in tumor suppression [].This entry represents the motor domain. |
