CATEGORY

structural protein

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm

basic FUNCTION	being a structural component of the eye lens
	involved in epithelial cell growth and migration and may contribute to lens fibre organisation
	contributing to the refractive index and transparency of lens
	major human lens protein, known to undergo several age-dependent changes
	may have a functional role related to actin, perhaps in 'shepherding' filaments to maintain the optical properties of the lens cytoplasm and normal fiber cell maturation
	age-dependent cleavage of CRYGS generates a peptide that binds to cell membranes

CELLULAR PROCESS	cell life, proliferation/growth
	cell organization/biogenesis

PHYSIOLOGICAL PROCESS

text	cell shape and cell size control

PATHWAY

metabolism

signaling

sensory transduction/vision

photoreception

a component

INTERACTION

DNA

RNA

small molecule

protein

when glutathione becomes bound to gammaS-crystallin, it causes it to bind in turn to the beta-crystallin polypeptides to form a dimer
