Among 543 lens proteins (blue dots) that were quantified via their 14 N vs. 15 N ratios (y-axis), there was a wide range of total protein abundance as estimated by MS/MS spectral counts (x-axis). Note that Calpain protease was long-lived, and the highly abundant α-, β- and γ-Crystallin proteins each had different levels of 14 N and 15 N.
WebNational Center for Biotechnology Information Webα-Crystallins are small heat-shock proteins that act as holdase chaperones. In humans, αA-crystallin is expressed only in the eye lens, while αB-crystallin is found in many tissues. α-Crystallins have a central domain flanked by flexible extensions and form dynamic, heterogeneous oligomers.
