Selection and sequence analysis of a cDNA clone encoding a known chorion protein of the A family.

RESUMO

Using as criteria the size, abundance and developmental specificity of hybridizing mRNA sequences, we have selected from our chorion cDNA library a clone corresponding to a specific chorion protein, A4--cl. Comparison between the clone sequence and the largely known sequence of A4--cl validates the use of the cDNA library for sequence analysis of the chorion multigene families. The two major chorion protein families, A and B, share certain structural similarities.
