Homology gene function determined

The c-myc gene, identified originally as the cellular homolog of the transforming determinant carried by avian myelocytomatosis virus, is altered in association with a broad spectrum of neoplasms. Consistent with the observation that altered c-myc is associated with tumors of diverse origin, it has been observed that normal c-myc is expressed in a variety of tissues. Thus, c-myc appears to encode a function associated with a ubiquitous metabolic pathway.
