title: Sequences of two cDNAs encoding silkworm homologues of Drosophila melanogaster squid gene.
abstract: The squid (sqd) gene of Drosophila melanogaster encodes a few isoforms of a heterogeneous nuclear (hn) RNA-binding protein. We isolated two types of cDNAs coding for homologues of the Sqd protein from the silkworm Bombyx mori. The two predicted amino acid (aa) sequences are identical up to aa 280 and then diverge. The silkworm and fruit fly proteins share 80% homology in the RNA-binding motif region. These cDNAs detect 2.0-, 1.8- and 1-kb mRNAs in the middle and posterior silk glands.
