title: Purification and characterization of a gamma crystallin from mouse lenses.
abstract: A gamma-crystallin has been purified by a two-step column chromatography from an extract of water soluble lens proteins from (101/ E1xC3H /E1)F1 mice. About 17% of the water soluble lens protein in normal mice is represented by this gamma-crystallin. The protein has been shown to be absent in cataractous lenses of Nop /+ mice after isoelectric focusing of water soluble lens proteins. It has a MW of 20,000. Amino acid analysis reveals the occurrence of eight cystein residues, which is considered to be high compared to other crystallins. The protein might play an important role in cataractogenesis.
