该基因编码的蛋白质是一种含有5'-肌醇磷酸酶的sh2，参与调节胰岛素功能。编码蛋白在表皮生长因子受体转换和肌动蛋白重塑的调控中也起着重要作用。此外，该基因支持乳腺癌的转移生长，是乳腺癌的一个有价值的生物标志物。[由RefSeq提供，2009年1月]
The protein encoded by this gene is an SH2-containing 5'-inositol phosphatase that is involved in the regulation of insulin function. The encoded protein also plays a role in the regulation of epidermal growth factor receptor turnover and actin remodelling. Additionally, this gene supports metastatic growth in breast cancer and is a valuable biomarker for breast cancer. [provided by RefSeq, Jan 2009]
