**Function**

This gene encodes a protein belonging to the sprouty family. The encoded protein contains a carboxyl-terminal cysteine-rich domain essential for the inhibitory activity on receptor tyrosine kinase signaling proteins and is required for growth factor stimulated translocation of the protein to membrane ruffles. In primary dermal endothelial cells this gene is transiently upregulated in response to fibroblast growth factor two. This protein is indirectly involved in the non-cell autonomous inhibitory effect on fibroblast growth factor two signaling. The protein interacts with Cas-Br-M (murine) ectropic retroviral transforming sequence, and can function as a bimodal regulator of epidermal growth factor receptor/mitogen-activated protein kinase signaling. This protein may play a role in alveoli branching during lung development as shown by a similar mouse protein.

SPRY2 is a negative feedback regulator of multiple receptor tyrosine kinases (RTK's) including receptors for fibroblast growth factor (FGF), epidermal growth factor (EGF), and hepatocyte growth factor (HGF). Antagonization of growth factor mediated pathways, cell migration, and cellular differentiation occurs through the ERK pathway. Spry2 can also enhance EGFR signaling by sequestering CBL. Spry gene expression has been reported silenced or repressed in cancer of the breast, liver, lung, prostate, and in lymphoma. Human spry2 expression is localized to the microtubules in unstimulated cells. All sprouty isoforms inhibit the ERK pathway by themselves, but can also form heterodimers and homodimers which have enhanced inhibition.

### Famous quotes containing the word function:

“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 mother’s and father’s attitudes toward the child correspond to the child’s own needs.... Mother has the *function* of making him secure in life, father has the *function* of teaching him, guiding him to cope with those problems with which the particular society the child has been born into confronts him.”

—Erich Fromm (1900–1980)

“Our father has an even more important *function* than modeling manhood for us. He is also the authority to let us relax the requirements of the masculine model: if our father accepts us, then that declares us masculine enough to join the company of men. We, in effect, have our diploma in masculinity and can go on to develop other skills.”

—Frank Pittman (20th century)
