Myosin Type I - ț̢
A subclass of myosins found generally associated with actin-rich membrane structures such as filopodia. Members of the myosin type I family are ubiquitously expressed in eukaryotes. The heavy chains of myosin type I lack coiled-coil forming sequences in their tails and therefore do not dimerize.
Synonyms :
Myosin Type II - ț̢
The subfamily of myosin proteins that are commonly found in muscle fibers. Myosin II is also involved a diverse array of cellular functions including cell division, transport within the GOLGI APPARATUS, and maintaining MICROVILLI structure.
Synonyms :
Myosin Type III - ț̢
A subclass of myosins originally found in the photoreceptor of DROSOPHILA. The heavy chains can occur as two alternatively spliced isoforms of 132 and 174 KDa. The amino terminal of myosin type III is highly unusual in that it contains a protein kinase domain which may be an important component of the visual process.
Synonyms :
Myosin Type IV - ț̢
A subclass of myosin found in ACANTHAMOEBA. It is a non-filamentous myosin containing a single 180-kDa myosin heavy chain.
Synonyms : HMWMI, High Molecular Weight Myosin I, Type IV, Myosin
