Abstract
Tyrosine-specific phosphorylation events serve to modulate cell to cell interactions during the normal growth and development of many vertebrate tissues. Numerous studies have been performed on the involvement of growth factor receptor tyrosine kinases (RTKs) in inner ear function. Many RTKs, however, have only been recently identified. and their expression patterns have not yet been systematically examined in all tissues. In this study, we surveyed mouse inner ear transcript sequences for the presence of RTKs using a degenerate-PCR based methodology. Isolates encoding RTKs that had and had not been previously identified in the inner ear were obtained. Our data reveals the presence of numerous RTKs in the inner ear that have not yet been studied in the context of inner ear and demonstrates the usefulness of RT-PCR analysis in identifying genes involved in inner ear function.
