CC   -!- FUNCTION: Central component in molecular interactions underlying sperm
CC       crawling. Forms an extensive filament system that extends from sperm
CC       villipoda, along the leading edge of the pseudopod.
CC   -!- SUBCELLULAR LOCATION: Cell projection, pseudopodium. Cytoplasm,
CC       cytoskeleton.
CC   -!- TISSUE SPECIFICITY: Sperm.
CC   -!- MISCELLANEOUS: Around 30 MSP isoforms may exist in C.elegans.
