Comments
Comments	required for property function of adhesins, may help localize adhesins to tip organelle, part of the cytoskeleton-like Triton shell [PUB_0088]; protein not detectable in M. genitalium [PUB_0091]; homologous to the filamentous coiled-coil portion of myosin type II heavy chain [PUB_0093]; high Pro content, low pI, central acidic Pro-rich domain [PUB_0089]; required for gliding [PUB_0091]; Pich et al showed that MG_218 codes for two proteins -- HMW2 and HMW2-s [PUB_0803]; the M. pneumoniae homolog has also been showed to code for two proteins [PUB_0804]. Pich et al also showed that MG_218 knockouts exhibit reduced gliding motility and that the MG_218 N-terminus is required for proper terminal organelle architecture [PUB_0803].
