Beta Gamma Crystallin - Function

Function

The main function of crystallins at least in the lens of the eye is probably to increase the refractive index while not obstructing light. However, this is not their only function. It is becoming increasingly clear that crystallins may have several metabolic and regulatory functions, both within the lens and in other parts of the body. More proteins containing βγ-crystallin domains have now been characterized as calcium binding proteins with Greek key motif as a novel calcium-binding motif.

Famous quotes containing the word function:

    The uses of travel are occasional, and short; but the best fruit it finds, when it finds it, is conversation; and this is a main function of life.
    Ralph Waldo Emerson (1803–1882)

    Advocating the mere tolerance of difference between women is the grossest reformism. It is a total denial of the creative function of difference in our lives. Difference must be not merely tolerated, but seen as a fund of necessary polarities between which our creativity can spark like a dialectic.
    Audre Lorde (1934–1992)

    ... the function of art is to do more than tell it like it is—it’s to imagine what is possible.
    bell hooks (b. c. 1955)
