GPB2基因编码功能及结构描述
该基因编码的蛋白与表皮生长因子受体结合，包含一个sh2结构域和两个sh3结构域。它的两个SH3结构域直接与其他蛋白质富含脯氨酸的区域形成复合物，其SH2结构域与酪氨酸磷酸化序列结合该基因与线虫的sem5基因相似，参与信号转导途径。已经发现了两个编码不同亚型的选择性剪接转录变体。[由RefSeq提供，2008年7月]
The protein encoded by this gene binds the epidermal growth factor receptor and contains one SH2 domain and two SH3 domains. Its two SH3 domains direct complex formation with proline-rich regions of other proteins, and its SH2 domain binds tyrosine phosphorylated sequences. This gene is similar to the Sem5 gene of C.elegans, which is involved in the signal transduction pathway. Two alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
