1) To know the protein composition of the streaming birefringent aqueous extracts of squid muscle, the extracts of squid were subjected to a fractional precipitation by dialysing against the solutions of different ionic strengths, the aqueous extracts of carp, spiny lobster, and blue crab being treated similarly for reference. 2) The proteins which precipitate by dialysis from the extracts of squid showed streming birefringence (SB), when suspended in water. Thus, SB of the extracts was attributed to this protein fraction (Table 4). 3) From the data obtained by the fractional precipitation, the proteins contained in the aqueous extracts were divided into four fractions, the composition of the extracts being discussed (Tables 1 and 2, Fig. 1). Hereby, it was suggested that both myosin-like protein and actomyosin-like protein might be present in the extracts of squid and might be responsible for SB.
