Definition
English
:
A subclass of
crystallins
that provides the majority of refractive power and translucency to the lens (LENS, CRYSTALLINE) in
VERTEBRATES
.
Alpha-crystallins
also act as
molecular chaperones
that bind to denatured
proteins
, keep them in solution and thereby maintain the translucency of the lens. The
proteins
exist as large oligomers that are formed from
ALPHA-CRYSTALLIN A CHAIN
and
ALPHA-CRYSTALLIN B CHAIN
subunits.
