| myosin | <protein> A family of motor ATPases that interact with F actin filaments. An increasing number of different myosins are being described. (See myosin light chains, meromyosin.) Myosin I is a low molecular weight (111-128 kD) form found in protozoa Acanthamoeba and Dictyostelium) that does not self assemble and is found in the cytoplasm as a globular monomeric molecule that can associate with membranes and transport membrane vesicles along microfilaments. Brush border Myosin I is a single headed myosin found in the microvilli of vertebrate intestinal epithelial cells, linking the membrane to the microfilament core. There is a single heavy chain of 119 kD and multiple (3 or 4) calmodulin light chains. The heavy chain has a C terminal domain that binds to acidic phospholipids. Myosin II is the classical sarcomeric myosin that self assembles into bipolar thick filaments. Myosin II is a multimeric protein (440 kD) with two heavy chains (200 kD) and two pairs of light chains (17-22 kD) in each hexamer. Between species and tissues there are considerable variations in the properties of Myosin II (see myosin light chains, meromyosin). Cytoplasmic myosin II is a family of sarcomeric myosin like proteins, also hexameric, responsible for force generation by interaction with microfilaments. There are two heavy chains (up to 240 kD) and two pairs of light chains (15-20 kD), the self assembled filaments are shorter than those of the sarcomere. The MYO2 gene product is an unconventional myosin from yeast involved in polarized secretion. MYO2 may be similar to dilute myosin from mouse and p190 protein from vertebrate brain. Scallop myosin is directly calcium regulated (through regulatory and essential light chains) and is more similar to sarcomeric myosin than to the nonsarcomeric myosins. Smooth muscle myosin has two 200 kD heavy chains, two regulatory 20 kD light chains that can be phosphorylated, altering its binding to the heavy chains which induces a conformational change that renders the myosin active and two 17 kD light chains.

| myosin atpase | <enzyme> An enzyme that catalyses the hydrolysis of myosin ATP in the presence of actin to form myosin ADP and orthophosphate. This reaction is the immediate source of free energy that drives muscle contraction. In the absence of actin, myosin atpase activity is low and requires calcium ions. Chemical name: Myosin ATP phosphohydrolase (actin-translocating) Registry number: EC 3.6.1.32 (12 Dec 1998) |
| myosin filament | One of the contractile elements in skeletal, cardiac, and smooth muscle fibres; in skeletal muscle, the filament is about 10 nm thick and 1.5 um long. (05 Mar 2000) |
| myosin heavy chain | <protein> See myosin: do not confuse with heavy meromyosin which is a subfragment of the heavy chain of myosin II. (18 Nov 1997) |
| myositis |

| myomectomy |
An operation to remove a myoma, or fibroid. A myomectomy for a submucous fibroid is often possible at hysteroscopy; a myomectomy for an intramural fibroid (located within the wall of the uterus), usually requires an open operation, or laparotomy; a myomectomy for a subserous fibroid can be possible at laparoscopy.

| myometrium |
The muscular wall of the uterus, surrounding the endometrium. The myometrium contracts (1) during menstruation perhaps causing dysmenorrhea, and (2) during miscarriage or labor to deliver the conceptus. See also myoma (or fibroid) and adenomyosis.
