RT   "Expression of spicule matrix protein gene SM30 in embryonic and adult
RT   mineralized tissues of sea urchin Hemicentrotus pulcherrimus.";
RL   Dev. Growth Differ. 38:687-695(1996).
CC   -!- FUNCTION: Matrix protein of the sea urchin embryo spicule. The function
CC       of the matrix proteins is to direct crystal growth in certain
CC       orientations and inhibit growth in others (By similarity).
CC       {ECO:0000250}.
CC   -!- TISSUE SPECIFICITY: Spines and tube feet.
CC   -!- DEVELOPMENTAL STAGE: Expression first detected around the onset of
CC       spicule formation and rapidly increased with the growth of spicules.
