RT   "Molecular mechanism of the nacreous layer formation in Pinctada maxima.";
RL   Biochem. Biophys. Res. Commun. 269:213-218(2000).
CC   -!- FUNCTION: May be specifically involved in the formation of the nacreous
CC       layer. {ECO:0000269|PubMed:10694502}.
CC   -!- SUBUNIT: Heterooligomer; disulfide-linked. Pif97, Pif80, N16 and other
CC       proteins form a complex (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted, extracellular space, extracellular
CC       matrix {ECO:0000269|PubMed:10694502}.
CC   -!- TISSUE SPECIFICITY: Component of conchiolin, the organic matrix of
CC       nacre. Only expressed in the dorsal region of the mantle.
CC       {ECO:0000269|PubMed:10694502}.
CC   -!- SIMILARITY: Belongs to the N16 matrix protein family. {ECO:0000305}.
