Abstract

A rat inner ear complementary DNA (cDNA) library containing 1.9 ×106 recombinants was constructed and evaluated. Inserts averaged 2.0 (±2.1) kilobases in length. A subset of inserts was screened for site of expression. Two cDNA transcripts were isolated based on cochlear expression restricted to the spiral ganglion. One transcript showed a high degree of homology to several long interspersed DNA elements, neuron-specific nuclear transscripts thought to be involved in gene regulation. The second transcript showed no homology to known sequences and appears to encode a neuron-specific protein of about 248 amino acids. The library can be used to identify proteins important for inner ear function and disease.
