CC   -!- FUNCTION: Major component of the striated microtubule-associated fibers
CC       (SMAFs; system-I-fibers).
CC   -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton.
CC   -!- DOMAIN: Consists of a small non-helical N-terminal domain and a rod
CC       domain with a 29 residue repeat pattern based on four heptads followed
CC       by a skip residue. This alpha-helical protein is characterized by the
CC       ability to form a special segmented coiled coil and to assemble into
CC       striated fibers of 2 nm protofilaments (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the SF-assemblin family. {ECO:0000305}.
