Asymmetric/Biological Unit(hide GO term definitions)

Chain A,B,C (CRBB3_HUMAN | P26998)

molecular function
	GO:0005515	protein binding	Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
	GO:0005212	structural constituent of eye lens	The action of a molecule that contributes to the structural integrity of the lens of an eye.
biological process
	GO:0007601	visual perception	The series of events required for an organism to receive a visual stimulus, convert it to a molecular signal, and recognize and characterize the signal. Visual stimuli are detected in the form of photons and are processed to form an image.
