Contribution

It identifies specific sequence differences in MIP between humans and chickens, highlighting evolutionary and functional distinctions.

Findings

Sequence differences in MIP between humans and chickens.

Potential implications for lens biogenesis and maintenance.

Insights into evolutionary divergence of lens proteins.

Abstract

The major intrinsic protein (MIP) of the lens fiber cell membrane plays a role in lens biogenesis and maintenance. Its polypeptide chains span the membrane six times, and the protein is naturally divided into two halves. We use modern sequence analysis to identify differences between halves for humans (common to animals) and chickens (common to birds).
