Role of crystallin insolubilization in cataract formation

ABSTRACT

This work aimed to study the electrophoretic pattern of lens proteins and to study the pathological variation in lens protein in cataract to decide if cataract results from insolubilization of lens protein or due to appearance of a new type of protein. Also, decide if these changes in lens protein composition occur in equal proportion among various types of cataract. The results stated complete absence of crystallin in the water soluble moiety of both nuclear cataract and cortical cataract. There is an increase in proteins of high molecular weight and decrease in low molecular weight protein. Bs crystallin is incorporated into the high molecular weight aggregates of the water insoluble moiety of lens protein
