Localization of a highly divergent mammalian testicular alpha tubulin that is not detectable in brain.

abstract：:In self-renewing tissues such as the skin epidermis and the bone marrow, Myc proteins control differentiation of stem cells and proliferation of progenitor cell types. In the epithelium of the small intestine, we show that c-Myc and N-Myc are expressed in a differential manner. Whereas c-Myc is expressed in the prolif...
