Non-actin contractile MFS exist in Protozoa. Their chemical constitution is partially known. They are ATP-independent, but their various physiological characters can be ultrastructurally grouped into two types: either, as it is the case for actin, they are closely associated to the endoplasmic reticulum apparatus, or they form myonemal bundles which are not related to any other organelle.
非肌动蛋白收缩性微丝体系存在于原生动物中。它们的化学组成部分已知。它们不依赖ATP，但从超微结构来看，它们的各种生理特征可分为两类：要么像肌动蛋白那样，与内质网紧密相关；要么形成与任何其他细胞器都无关的肌原纤维束。
